Dreamweaver Lightbox exclude a named anchor
I'm working on a non-flash backup for my baby hats catalog. I use Dreamweaver CS5.5 and a lightbox that I downloaded from the widgets to display the images. However, my first image and then two inbetween each hat are other <a></a> tags. The first serves as a named anchor for the navigation and the second opens a .pdf. When you view the lightbox images these two appear as the "waist lightbox is loading" circle image. You have to click "next" twice to get to the next actual image. Is there a way to exclude these two instances? I'm afraid my end users won't know to click "next" twice to see the next image.
Thanks.
My code is on this page:
http://www.ecochicknits.com/Babyold.html
Use 'data-lightbox' attribute to combine each set of hats into its specific gallery, thereby restricting each lightbox instance to only show 4 or 5 of those hat images and not all images available on page. Read http://lokeshdhakar.com/projects/lightbox2/ (How to Use) section for more details on how you can do this
On a sidenote, why are you including the jquery.js and lightbox.js 3 times each on your page? Your HTML page, Lines 159-167:
<script src="Scripts/jquery.js" type="text/javascript"></script>
<script src="Scripts/lightbox.js" type="text/javascript"></script>
<script src="SpryAssets/SpryMenuBar.js" type="text/javascript"></script>
<script src="Scripts/jquery.js" type="text/javascript"></script>
<script src="Scripts/lightbox.js" type="text/javascript"></script>

<script src="Scripts/lightbox.js" type="text/javascript"></script>
<script src="Scripts/jquery.js" type="text/javascript"></script>
<script src="Scripts/lightbox.js" type="text/javascript"></script>
You can remove the lines I've struck off here. You're already calling these scripts in the first 2 lines.

Dreamweaver CS5.5 - Header, Named Anchor and Hidden text
Hello,
I am a relative novice when using dreamweaver. I don't use it in an official capacity, rather than as a Hobby.
I have created a webpage with a position fixed header, displaying a Jump Menu/Drop Down Menu linking to named anchors on the page. I have a css linked to the page using:
#header {
text-align: center;
width: 100%;
background-color: #CFC;
position:fixed;
top:0;
left:0;
z-index:1000;
When I use the menu to jump to the named anchor (#a04x01), the page will display the text, but the "Chapter One" text is hidden behind the header.
My question is how to either offset the named anchor so when it is jumped to, it appears 200px above where it is meant to (So displaying "Chapter One")?, or to alter the header so it is in a solid state so the text cannot scroll "beneath" it, rather the page considers the bottom on the header the top of the page?.
Any suggestion or solves would be gratefully accepted.
PS: If needed, I can supply the .html page, & .css
Thank you
Regards
TjStormRemove position:fixed from your <header> and you won't have that problem. Fixed positioned elements are not part of the normal document flow as they are at fixed coordinates at all times.
This example uses fixed elements with ample top- and bottom-padding between sections. View source to see the code.

How to close one browser window and return to a named anchor on a page in another window
I'm working on a website that has several book images at the bottom of each page. I have set it up so when the user clicks on a book another smaller browser window opens up with a description of the book. At the bottom of book description window, I have a close button which I added the window.close() behavior to. But I'd like to not just have the window close but return the user to the bottom of the original page where I have the books, an area that I have applied a named anchor to. Any ideas on how I can get this done.
I'd appreciate any and all help.I haven't tried to customize this lightbox extension much. But I'm pretty sure the size of the box is pre-determined by image size. Bigger image, bigger box. And that is coded into one of the Lightbox javascript libraries.
As to placing a link in the caption, sure. Just paste your html link code into the Lightbox Caption Panel like so.

Named Anchors and the HTML doc
Normally, when using the the default "Flash Only" setting in the HTML publish settings, you can set the dimensions to 100 x 100 percent. This will make the Flash movie fill the browser window and resize with the browser.
I'm using named anchors and am using the "Flash with Named Anchors" setting in the HTML publish settings. Everything else is the same as when I use the "Flash Only" template. However, when I publish this HTML document it is not filling the browser window correctly. Instead, the movie is being displayed as if I had set the movie size to 100 x 100 pixels instead of percent. In other words, the Flash movie is squeezed into a size of 100 x 100 pixels. Something is causing it to misinterpret percent as pixels.
I've looked at the HTML document and it correctly says width="100%" height="100%". This problem occurs in Firefox 3.6. Everything displays correctly in IE8 and Safari 5. Thank you in advance to anybody with advice or a solution.helpall wrote:

It has nothing to do with what Dreamweaver will let you do
nor not do, it has to do with what you the panels are "told" to do
in certain situations. In this case you want to open a specific
panel, preferably based upon the anchor name that you're already
using. Take a look at the URL Utilities sample page, in particular
at the last example:
http://labs.adobe.com/technologies/spry/samples/utils/URLUtilsSample.html
This means you'd need to get the full Spry download:
http://labs.adobe.com/technologies/spry/home.html
If you wanted, you could add a query string parameter like
the above example does, but that might mean changing a lot of
links.
Or you could modify the example code above to "slice" out the
first letter of the anchor and figure out the index of the tab to
show (they use a 0 based index, so 'a' would 0 and 'z' would be 25.
Try the following:
<script type="text/javascript">
<!--
var hash = window.location.hash;
if(hash){
// get the character code of the upper case of the first
letter then subtract 65
// 'A' has a character code of 65, so the subtraction gets
our tab index from 0 to 25
var charCode = hash.toUpperCase().charCodeAt(0)-65;
if(charCode < 0 || charCode > 25){ // If not in A-Z
range, use default for 'a'
charCode = 0;
else{
// Default to tab 0, or 'a' when no hash present
var charCode = 0;
//The defaultTab value checks to see if the url param is
defined. If it is not, it sets it to 0.
var
var TabbedPanels1 = new
Spry.Widget.TabbedPanels("TabbedPanels1", {defaultTab: charCode });
//-->

Help!! Why are of my sitemap links not landing on their named anchors?
I've just manually completed a sitemap for my dreamweaver 8 website: http://www.ggordontowerofbabel.co.cc The first 2 pages are fine, with all the links landing just at the spot I want them to.
However, on the 3rd page, they land on the spot, but as soon as the page is fully loaded, it jumps off indiscriminately to another part of the page? This is only a problem once it is loaded onto the server for anyone to access. However, all is fine locally, where only, "MyMediaPage.htm#MyFilm" is applied to the link, but once on the server, I add the full url http://www.ggordontowerofbabel.co.cc//MyMediaPage.htm#MyFilm
Again, all is fine on the first 2 pages on the server, and I'm using the same method.
After removing code from the body tag, it helped only partially. However, now the link lands on the next named anchor instead, almost as catch-up. So, while it may briefly land on its target, it still shoots onto the previous or next one. Please help!!Hi
Thank you for your help. Since you didn't experience the same problem, I checked the page in IE. It was fine. So, it seems that it is only a Mozilla Freezefox problem, and will need to figure out how to fix that.
I'm gratefull too for your additional information, as all constructive criticism is very welcome, so I will now change the red font colour as you suggested. If you thought it was bad then, I had just changed the font itself from TN Roman to Ariel, so think yourself lucky your eyes were spared that
I've also considered your excellent advice on running the page throught the validator. I've done that. However, reading and understanding html coding is torture for me, as simple, plain English would help me better.
Truly grateful. -
Why is my named anchor link not working
Can someone please help.
I am a novice at Dreamweaver - but my website works well with almost all links working.
Situation :
The problem lies on the following page www.ozonesystems.co.uk/airunits
There are 7 links in the table which point to Named Anchors
While browsing in Internet Explorer, all links work perfectly
While in MozillaFirefox or Google Chrome, only the fist 2 links work. The remaining 5 links do not redirect me to the appropriate section (anchor) on the page. There is no error message.
Can anybody please help with this problem?
Thanks - Roy MarnewickHi Jon
Many thanks for your reply and comments.
I am a real novice. I used ApDiv's only because I had a problem in getting images and text to reside where I intended them to be placed - and this was the only way which I discovered would achieve the result I required. I do not want to re-invent the wheel, so I will just live with problems which may appear to those using different size text, and hope there are minimal visitors doing this!
I will visit the link which you have provided to resolve the minor errors. Thanks for the link.
It is good to hear that (hopefully) the problem is not as widespread as I thought it might be as you did not experience a problem while browsing with Firefox36 and Chrome40. I will try and clear the browser cache as suggested - do not know how - but will try and find out.
Thanks & Regards

Jump to a Named Anchor when loading an HTML doc
I have a CollapsiblePanel with a Content Link to a Named
Anchor in info.html and I thought I could use loadURL() to load the
page into the Div "thetext" but it does not work. Can Spry Jump to
a Named Anchor when it loads an HTML doc?

Spry.Utils.updateContent('thetext',

And I also tried:
Spry.Utils.loadURL('thetext', '/information2.php#Insurance')

Sure - just make the link to the anchor:
<a
href="page.php#anchor"
onclick="popupscript('page.php#anchor');return false;">
Open my popup window</a>
Making the link attribute (href=) the same as the popup
window means that
people who are visiting your site with javascript turned off
will also
get the information from the page. The 'return false' in the
onclick
event means that the href won't fire if javascript is turned
on.

Hi folks.
The problem I have is that after a few years of running my
band's website (basic HTML using Dreamweaver) we decided to get a
'pro' to build us a new one. Well they did and now it's impossible
for me to do anything with it apart from very basic text updates
etc.
The first problem is that the site is PHP?? and also all the
page layouts are determined by CSS and any page content is a basic
file that loads into the pages, if you see what I mean.
I am ok with basic editing, updating the news adding shop
items etc but I have now hit a brick wall and the 'pro' is now
unavailable!
What I am trying to do is put a link in the main menu on the
left of the front page that jumps to a named anchor on the shop
page to take you directly to the 'Downloads' section at the bottom.
I can get it to either just jump to the shop page (but at the top)
as normal, or to jump to the anchor as I want, but with the shop
page outside the page/frame it sits in.
How do I do this?

The links are from the teacher names in the right hand column. The named anchor sits between the masthead image and the navigation menu. -

Target Named Anchor in a Spry Collapsible Panel from a different page
Let me start by saying I have combed this forum (and others) looking for a resolution to this. I am familiar with David Powers solution on Foundationphp.com and am using that code in project to open the collapsible panel from a separate page and it works beautifullly. The problem I have is that I want the browser to move down to a specific named anchor inside that opened collapsible panel when clicked from a different page.
Snippets of my current code here.
Below is the code that I have on an image that when clicked goes to the correct page and opens Panel1. Works Perfectly!
<a href="bamboo-species.php?col1=open#CollapsiblePanel1"><img src="images/Content/Photos/HomeScroll/blackTmbor.jpg" width="227" height="175" /></a>
Below is the link to the .js file and the script in the head of the target page
<script type="text/javascript" src="SpryAssets/SpryURLUtils.js"></script>
<script type="text/javascript">
// Grabs the values of the URL parameters for the current URL.
var params = Spry.Utils.getLocationParamsAsObject();
</script>
Below is the code that I have on the target page for Panel1
<script type="text/javascript">
var CollapsiblePanel1 = new Spry.Widget.CollapsiblePanel("CollapsiblePanel1", {contentIsOpen:params.col1 ? true : false},{duration: 1000});
</script>
If I have a named anchor say <a name="species1" id="species1"></a> down in the page, how do I target that named anchor from my link on the separate page. I have tried adding the #species1 to the end of the link on the link page (see below) but with no luck. I believe those were the instructions on foundationphp.com site.
<a href="bamboo-species.php?col1=open#CollapsiblePanel1#species1"><img src="images/Content/Photos/HomeScroll/blackTmbor.jpg" width="227" height="175" /></a>
I hope (and suspect) that this is an easy fix, I just do not know what it is. Any help or direction where to look is greatly appreciated.I once had the same issue can created a small function that allows me to "jump" to a element.
function scrollTo( element ){
var stylize = function( element){ return !+"\v1" ? element.currentStyle : document.defaultView.getComputedStyle( element , null ) },
getPosition = function( element ){
// based on the SpryEffect's module:
var computedStyle, tryComputedStyle,
position = { x: 0, y: 0 };
if ( element.style.left && /px/i.test(element.style.left) ){
position.x = parseInt(element.style.left, 10); // without padding
} else {
computedStyle = stylize( element );
var tryComputedStyle = computedStyle && computedStyle.left && /px/i.test( computedStyle.left );
if (tryComputedStyle)
position.x = parseInt( computedStyle.left, 10 ); // without padding, includes css
if(!tryComputedStyle || position.x == 0) // otherwise we might run into problems on safari and opera (mac only)
position.x = element.offsetLeft; // includes padding
if ( element.style.top && /px/i.test(element.style.top) )
position.y = parseInt( element.style.top, 10); // without padding
else
if ( !computedStyle )
computedStyle = stylize( element );
var tryComputedStyle = computedStyle && computedStyle.top && /px/i.test( computedStyle.top );
if ( tryComputedStyle )
position.y = parseInt( computedStyle.top, 10 ); // without padding, includes css
if( !tryComputedStyle || position.y == 0 ) // otherwise we might run into problems on safari and opera (mac only)
position.y = element.offsetTop; // includes padding
return position;
scroll( 0, getPosition( element ).y );
So now we have a scrollTo function that accepts a pure HTML element as argument, all what is left to do is figure out if we have a hash, and if the anchor exits on the page.
( hopes this works, i wrote it without testing, but you get the general idea ):
if( window.location.hash ){
var hash = window.location.hash.substr(1), // remove the # from the hash
element;
// as anchors can also be used with id attributes, check that first,
element = document.getElementById( hash );
// maby we used name="" attribute
if( !element && ( element = document.getElementsByName( hash )) ){
element = element[0];
// if we have a match:
if( element ){
// give the collapsible panel some time to init and update the DOM;
setTimeout(function(){ scrollTo( element ) },0);

Links to id's and named anchors within a page in an iframe do not open in firefox
In order to force layout of my liquid website, I use i-frames to display content . It is all on my sight www.rdelutherie.com, and I am not displaying pages from other sights. The links to sections of pages from within the same page do not work in firefox.
I have had this problem before with named anchors, and in moving up to html5 and in making my site accessible for people with dissabilities, I started using <nav> eliments... and changed from named anchors to links to ID's like this:
In an unordered list I have these:
<pre><nowiki> <li><a href="#s1">Subject 1:</a></li>
</nowiki></pre>
They link to sections of the same page like this one:
<pre><nowiki>
<section id=s1>
<h2>Subject 1:</h2>
<p>Blah blah blaaaaah, and bla bla!</p>
</section></nowiki></pre>
Last time I researched this problem (a year or more ago), I was told that it was because of a security risk (something about being able to count views...and other peoples proprietary and copyrighted material), but the vaguely described reasoning made little to no sense to me nor many others, who can not even link to our own stuff. The Mozilla developers were rather abrupt and some were even rude in telling us to live with it, instead of trying to come up with a solution or work around, and closed the post and disallowed further posting.
The problem still persists, and although I am not a programmer, I have a real hard time believing that it is impossible for Firefox to distinguish between links contained within a document and site, from those on different sights, domains and what have you.
As far as I know, no other browsers have this problem, so if it is such a big security risk, what is to stop someone with malicious intentions, from just using M$ IE, to bring their evil plan to fruition?
In keeping with "Making the web a better place": Please address this problem, and find a solution, workaround, or at least explain why it is impossible.
Bob EnglishThanks again jscher2000,
I know exactly what you mean, but I have had other page display problems with adjacent columns where one side does not display completely and seems to be conforming to the other ones height... hence the height settings and other tricks to force things to be acceptable.
I am far from understanding code, and most of the solutions, including the one in the link you posted do not have the information a novice like me would need to implement them successfully. Most of them are written for people much more advanced. Without it telling me where exactly to put the code, point to it, what I can (and should) change and remove elsewhere because of it... I am at a loss. I don't know the basics, and have tried hard to understand them, but it is not like electrical circuits, physics and other things that I can understand naturally and with ease.
I will look into it further in a few days, meanwhile I have to attend to my real work that doesn't even pay the bills completely: guitar building and repair, now that comes easy and naturally to me! -
RE: Named anchored objects
Albert,
In my case I was using a named anchored object to get a handle to an actual
service object. My named object that I registered in the name service was
an intermediary to which I did not maintain a connection. So I have not
explicitly tested what you are asking.
However, I too was not using a hard coded reference to the SO, and fail over
and load balancing worked fine. The functions of fail over and load
balancing are not done by the service object but by the name service, proxy
and router. Since you are getting a proxy back any time you do a lookup in
the name service I would think that fail over should work with any anchored
object that is registered in the name service. When you do a RegisterObject
call you will notice that one of the arguments is the session duration,
which implies to me that fail over will be handled the same as for service
objects.
Load balancing adds another wrinkle. Load balancing is handled by a router.
You must get a proxy to the router and not a proxy to an instance of the
object that the router is doing the load balancing for. In the latter
scenario you will be bypassing the router. If you are creating, anchoring
and registering your objects dynamically you will not have a router so you
will not be able to load balance! This applies even if the objects are
instantiated within partitions that are load balanced because you will still
be getting proxies back to a particular instance of the anchored objects.
There are ways to accomplish load balancing between objects that you
register yourself. However, the best solution will vary depending on the
actual problem trying to be solved. If you would like to discuss this
further, include a little more detail about the scenario you need to
implement and I will give you what I know.
BTY what I have outlined above also applies to getting references via a
system agent.

My question about both solutions (using Nameservice and agents) is:
If I reach a remote service object using either a BindObject or an agent, do
fail-over and load-balancing work the same way as they normally do when
using a hard coded reference to the SO.

Alexander,
I can not comment on the speed difference because I never tested it.
But, I
will say that we looked at the agent solution at a client sight
before. I
will give the same warning I gave them. If you go the agent direction
you
are now using agents for a purpose that they were not intended. Even
though
it technically works, as soon as you start using a piece of
functionality in
a way the developer did not intend it to be used you run the risk of
forward
compatibility problems. By this I mean, since agents were not
originally
intended to be used to look up service / anchored object references,
it may
not work in the future because it is not likely to be given
consideration in
any future design.
As we all know, programmers are always stretching the bounds of the
tools
they use and you may have a good reason (i.e. performance). I just
wanted to
let you know the possible risk.
One final note on a limitation of using system agents to obtain
references
to anchored objects. You can not access agents across environments.
So, if
you have connected environments and need to get references to services
in
another environment for fail-over or whatever, you will not be able to
do it
with agents.
Just some thoughts!

David,
The problem with dynamic binding is that in this case you have to keep
the reference to the service object somewhere. You don't want to call
"bindObject" every time you need to use this service object, "bind" is
a
time-consuming operation, even on the same partition. Keeping
reference
could be undesirable if your object could be moved across partitions
(e.g. business object).
The alternative solution is to use agents. You can create custom
agent,
make it a subagent of an active partition agent and use it as a
placeholder for whatever service you need. "FindSubAgent" works much
faster than "bindObject", we verified that and agent is "user-visible"
by its nature.

I actually determined it through testing. In my case I did not want
this to
happen and was trying to determine why it was happing. It makes sense
if
you think about it. Forte is trying to avoid making a remote method
invocation if it can.
Now, for anything more complex than looking locally first and if none

more
work. Using a naming scheme like Jez suggests below works well.

Subject: RE: multiple named objects with the same name and interface
David,
there's a mechanism used within SCAFFOLDS that allows the
location of the 'nearest' SO when more than one is available.
It involves registering each duplicated SO under three dynamically
built
names. The names include the partition, the node or the environment
name.
When wishing to locate the nearest SO the BO builds a SO name using
its
own partition and asks the name service for that.
If there is an SO registered under that name then it must be in the
same
partition and all is well. No cross partition calls.
If not, then the BO builds the name using its node and asks the name
service for that.
This means that if there is an SO outside the BO partition but still
on
the same node then this can be used. Again, relatively 'local'.
If neither of these work then the BO has to resort to an environment
wide search.
It may be that this approach could be adapted / adopted; I like it's
ingenuity.

Subject: RE: multiple named objects with the same name and

Sean,
First, thank you for your response. I have wondered about this fora
long time.
I looked at the documentation for ObjectLocationManager and on page
327
of the Framework Library and AppletSupport Library Guide indescribing
the BindObject method Forte says:
"The name service allows more than one anchored object (from
different
partitions) to be registered in the name service under the same
registration name. When you invoke the BindObject method with a
request
for a name that has duplicate registration entries, the BindObject
method finds an entry corresponding to an active partition, skipping
any
entries that do not. If no such active partition is found, or if the
requested name is not found in the name service registry, a
RemoteAccessException will be raised when the BindObject method is
invoked."

David,
First I will start by saying that this can be done by using named
anchored
objects and registering them yourself in the name service. There is
documentation on how to do this. And by default you will get mostof
the
behavior you desire. When you do a lookup in the name service
(BindObject
method) it will first look in the local partition and see if thereis
a
local copy and give you that copy. By anchoring the object and
manually
registering it in the name service you are programmatically creating
your
own SO without defining it as such in the development environment.
BTW
in
response to your item number 1. This should be the case there as
well.
If
your "mobile" object is in the same partition where the serviceobject
he is
calling resides, you should get a handle to the local instance ofthe
service object.
Here is the catch, if you make a bind object call and there is no
local
copy
you will get a handle to a remote copy but you can not be sure which
one!
It end ups as more or less a random selection. Off the top of myhead
and
without going to the doc, I am pretty sure that when you register an
anchored object you can not limit it's visibility to "User".

Subject: multiple named objects with the same name and interface
All,
More than once, I have wished that Forte allowed you to place named
objects with the same name in more than one partition. There aretwo
situations in which this seems desirable:
1) Objects that are not distributed, but are mobile (passed by value
to
remote objects), cannot safely reference a Service Object unless it
has
environment visibility, but this forces the overhead of a remote
method
call when it might not otherwise be necessary. If it were possibleto
place a copy of the same Service Object (with user visibility) ineach
partition, the overhead of a remote method call could be avoided.
This
would only be useful for a service object whose state could besafely
replicated.
2) My second scenario also involves mobile objects referencing a
Service
Object, but this time I would like the behavior of the calledService
Object to differ with the partition from which it is called.
This could be accomplished by placing Service Objects with the same
name
and the same interface in each partition, but varying the
implementation
with the partition.
Does anyone have any thoughts about why this would be a good thingor
a
bad thing?

In my case I was using a named anchored object to get a handle to an actual
service object. My named object that I registered in the name service was
an intermediary to which I did not maintain a connection. So I have not
explicitly tested what you are asking.
However, I too was not using a hard coded reference to the SO, and fail over
and load balancing worked fine. The functions of fail over and load
balancing are not done by the service object but by the name service, proxy
and router. Since you are getting a proxy back any time you do a lookup in
the name service I would think that fail over should work with any anchored
object that is registered in the name service. When you do a RegisterObject
call you will notice that one of the arguments is the session duration,
which implies to me that fail over will be handled the same as for service
objects.
Load balancing adds another wrinkle. Load balancing is handled by a router.
You must get a proxy to the router and not a proxy to an instance of the
object that the router is doing the load balancing for. In the latter
scenario you will be bypassing the router. If you are creating, anchoring
and registering your objects dynamically you will not have a router so you
will not be able to load balance! This applies even if the objects are
instantiated within partitions that are load balanced because you will still
be getting proxies back to a particular instance of the anchored objects.
There are ways to accomplish load balancing between objects that you
register yourself. However, the best solution will vary depending on the
actual problem trying to be solved. If you would like to discuss this
further, include a little more detail about the scenario you need to
implement and I will give you what I know.
BTY what I have outlined above also applies to getting references via a
system agent.

My question about both solutions (using Nameservice and agents) is:
If I reach a remote service object using either a BindObject or an agent, do
fail-over and load-balancing work the same way as they normally do when
using a hard coded reference to the SO.

Alexander,
I can not comment on the speed difference because I never tested it.
But, I
will say that we looked at the agent solution at a client sight
before. I
will give the same warning I gave them. If you go the agent direction
you
are now using agents for a purpose that they were not intended. Even
though
it technically works, as soon as you start using a piece of
functionality in
a way the developer did not intend it to be used you run the risk of
forward
compatibility problems. By this I mean, since agents were not
originally
intended to be used to look up service / anchored object references,
it may
not work in the future because it is not likely to be given
consideration in
any future design.
As we all know, programmers are always stretching the bounds of the
tools
they use and you may have a good reason (i.e. performance). I just
wanted to
let you know the possible risk.
One final note on a limitation of using system agents to obtain
references
to anchored objects. You can not access agents across environments.
So, if
you have connected environments and need to get references to services
in
another environment for fail-over or whatever, you will not be able to
do it
with agents.
Just some thoughts!

Subject: RE: multiple named objects with the same name and interface
David,
The problem with dynamic binding is that in this case you have to keep
the reference to the service object somewhere. You don't want to call
"bindObject" every time you need to use this service object, "bind" is
a
time-consuming operation, even on the same partition. Keeping
reference
could be undesirable if your object could be moved across partitions
(e.g. business object).
The alternative solution is to use agents. You can create custom
agent,
make it a subagent of an active partition agent and use it as a
placeholder for whatever service you need. "FindSubAgent" works much
faster than "bindObject", we verified that and agent is "user-visible"
by its nature.

David,
I actually determined it through testing. In my case I did not want
this to
happen and was trying to determine why it was happing. It makes sense
if
you think about it. Forte is trying to avoid making a remote method
invocation if it can.
Now, for anything more complex than looking locally first and if none
is
found give me any remote instance you can find, you will need to do
more
work. Using a naming scheme like Jez suggests below works well.

Subject: RE: multiple named objects with the same name and interface
David,
there's a mechanism used within SCAFFOLDS that allows the
location of the 'nearest' SO when more than one is available.
It involves registering each duplicated SO under three dynamically
built
names. The names include the partition, the node or the environment
name.
When wishing to locate the nearest SO the BO builds a SO name using
its
own partition and asks the name service for that.
If there is an SO registered under that name then it must be in the
same
partition and all is well. No cross partition calls.
If not, then the BO builds the name using its node and asks the name
service for that.
This means that if there is an SO outside the BO partition but still
on
the same node then this can be used. Again, relatively 'local'.
If neither of these work then the BO has to resort to an environment
wide search.
It may be that this approach could be adapted / adopted; I like it's
ingenuity.
Cheers,
Jez

Subject: RE: multiple named objects with the same name and

Sean,
First, thank you for your response. I have wondered about this fora
long time.
I looked at the documentation for ObjectLocationManager and on page
327
of the Framework Library and AppletSupport Library Guide indescribing
the BindObject method Forte says:
"The name service allows more than one anchored object (from
different
partitions) to be registered in the name service under the same
registration name. When you invoke the BindObject method with a
request
for a name that has duplicate registration entries, the BindObject
method finds an entry corresponding to an active partition, skipping
any
entries that do not. If no such active partition is found, or if the
requested name is not found in the name service registry, a
RemoteAccessException will be raised when the BindObject method is
invoked."
My question is: How did you discover that in the case of duplicate
registrations the naming service will return the local object if one
exists? This is not apparent from the documentation I have quoted.
Is
it documented elsewhere? Or did you determine it empirically?

Named Anchor linking from another document
I made a Named Anchor and linked from some text in another document. Great. Worked just fine. The only thing is it doesn't display the named anchor at the top of the page.
In other words the footer is at the bottom of the page and the named anchor in the middle of the page... not at the top. Like a #top would be.
Anyway to get it to the top of the page? Do I just need more content under it?
Much appreciated!Thanks for the help. I had no luck trying it out.
If possible, at: artdesignsneed.com/joeldoctor
Under menu choice "Treatment" then choose "TFP".... the first sentence has ..."Borderline PD developed..."
I wanted to link Borderline PD to:
Menu choice: Disorders... choose Personality... go down to "Cluster B" and there's Borderline PD.
The link worked but the named anchor "Borderline PD" is in the middle of the page.
Cheers if you can help.
If not, I'm going in the right direction.
Much appreciated. -
Named Anchored Obj-Environment Failover
Hi to all,
We connect from EnvA to EnvB giving the user directory parameter as / and
set the Environment Search Path
as EnvA:EnvB. From both environments we start and register
'/glob/obj1' named anchored objects with the same name.
From a client we connect to EnvA and bind to'/glob/obj1' when we shutdown EnvA partition it fails-over to
EnvB. And then we restart EnvA partition. We restart/rebind the client and
try to use object. We see that it is using the EnvB object.
Although we started the primary environment object again.
It is not using the search path. Once we shutdown secondary environment
it starts using primary environment object.
When we try to use relative path when we are binding the object
First parameter ('glob/obj1') No first slash. Trying 3rd parameter
for bind function or just using environment search path, Is is not able to
find the object. From nsls command I figured out that
under the root directory
/forte/UUID of ENVA/node
/site
/UUID of ENVB
/glob/obj1
names are available. When we use relative path (without slash)
is it trying to find /glob/obj1 under the /forte/UUID of ENVA
but we are registering the name under the root.
What is the reason of this odd behaviour or is this a bug?
Any answer will be appreciated,Hi Juliesmiley,
According to your description, I recommend you check the conditions required for an automatic failover.
• Primary replica and secondary replica are both configured for syschronous-commit mode and set to AUTOMATIC failover.
• All availability databases that are defined in the availability group must be in a SYNCHRONIZED state between the primary replica and the secondary replica.
• The Windows Server Failover Clustering (WSFC) cluster has quorum.
• The primary replica has become unavailable.
For more information, please review the following articles.
Failover and Failover Modes (AlwaysOn Availability Groups)
