Todd,
I'm calling resetTileIndex() in the begin display of the tiled views.
I'm attaching the code with this mail.
Outer tile: pgModelDistributionrMultiplePayeesTiledView
inner tile: pgModelDistributionrPayeeDetailsTiledView
Yes, Matt's mail helped me in resolving the first problem (submitting
the form on href click).
I have replaced the href from
<a
href="../Participant/pgModelDistribution?pgModelDistribution.linkNetDistribu
tion=&pageAttributes=">
$1,000 </a>
to
$1,000
and added a new javascript method as below:
function netDistFunc()
val = document.forms[0].elements["pageAttributes"].value;
_url =
"../Participant/pgModelDistribution?pgModelDistribution.linkNetDistribution=
&pageAttributes="+val;
>
document.forms[0].method = "post";
document.forms[0].action = _url;
document.forms[0].submit();
return false;
Now, I'm able to get the data entered by the user.
Thanks

Srinivas--
From where are you calling these methods, what event? Maybe you shouldsend
me the code for your nested tiled views--that's probably the easiest way
for
me to understand what's happening. Also, were any of Matt's
suppositions
correct?

RE: [iPlanet-JATO] Href click & tiled view display

Srinivas,
I hope that I am not oversimplifying your first question; repost if I do not
answer your question. Independent of JATO, HTML Form button sumbits will
include the scraping of data off the form input fields; the data will passed
as part of the body of the HTTP request. Therefore, you would expect to
receive all your inputs during the Button submit. In the case of a button,
a HTTP POST request is invoked. Href clicks, only submit the NVPs which are
encoded on the HREF URL. Therefore, it is impossible (under normal
circumstances) to retrieve the inputs from the FORM during the Href click.
In the case of a Href, a HTTP GET request is invoked. Some customers have
used a pattern in which Javascript is used to capture the Href onClick()
event to perform some runtime modifications to the HREF URL before the HTTP
GET request is submitted. I recommend to always have the LogProxy2 utility
running during development so that the HTTP requests and repsonses can be
debugged. If you setup the LogProxy2 (downloadable from this Group's Files
repository) then you would see the HTTP requests in the LogProxy2's console
window.
TiledView question: Remember, each TiledView requires a "primary
DatasetModel" which it uses for iteration of the tiles. It can be
confusing, but the API call of
<ContainerView>.getDefaultModel()
has no relation to the implementation class called DefaultModel. See the
Javadoc (excerp below)
/migtoolbox-1.1.1/doc/jato/api/com/iplanet/jato/view/ContainerView.html#getD
efaultModel()
"Returns this view's default model. The default model is typically used by
DisplayField children for default value storage (if they are not bound to
any other model). This method should always return a valid model instance.
Note that the default model need not be an actual instance of DefaultModel,
although this is usually the case."
Both of your TiledView's (inner and outer) are ContainerViews, each having
their own property for [get/set]DefaultModel(). Likewise, the ViewBean
parent of the outer TiledView is a ContainerView as well. With these facts
in mind, consider the behavior of the ModelManager. The ModelManager will
ensure that only once instance of specifically named model will be provided
during a request scope. Therefore, everytime that you make a call to
<ModelManager>.getModel(SomeModel.class)
no matter how many times you make this call during a request, the
ModelManager will ensure that you get the same object reference back.
Implicitly, you are asking for a Model with the exclusive name of
<ModelManager>.getDefaultModelInstanceName(SomeModel.class)
I believe that your problem is that you have the Primary Model of both the
inner and outer TiledView's set to the same instance of the DefaultModel
class. Therefore, the TiledViews are tripping over each other because they
are using the same Primary model. What I would do is change the constructor
of each TiledView to set an exclusive Primary model
// add to constructor of outer TileView
setPrimaryModel(getModelI(DefaultModel.class,"outer")
// add to constructor of inner TileView
setPrimaryModel(getModelI(DefaultModel.class,"inner")
remember to set the "size" of the Primary Model appropriately in the
beginDisplay() event of each TiledView before calling super.beginDisplay()

Subject: [iPlanet-JATO] Href click & tiled view display
Hi,
I'm facing the following two problems in JATO. Your help will be
appreciated.
1) Clicking a HREF.
I have a button and a href in a page. When I submit the page by
clicking the button, I'm able to
get all the user entered data (form elements) in handler method.
However, when I click
the href and I try to retrieve the data entered by the user in my
corresponding handler method, I'm
getting blank values.
How would I be able to get the user entered data upon clicking of a href
? I'm copying the sample
code for your reference.
// This returns me 5 values entered in the 5 tiles by the user.
public void handleBButtonRequest(RequestContext req)
throws ServletException, IOException
try
System.out.println("button clicked..");
pgSampleTiledView tiledView = getSampleTile();
System.out.println("\n\n\n\n@@@@@@@@@@@ No of tiles >>>
"+tiledView.getNumTiles());
int n = tiledView.getNumTiles();
for (int i=0; i<n; i++)
tiledView.setTileIndex(i);
System.out.println(i+".
"+tiledView.getTbValue().getValue().toString());
this.forwardTo(req);
catch (Exception ex)
ex.printStackTrace();
// This returns me 0 tiles and doesn't get into for loop
public void handleLinkModifyDistributionRequest(RequestContext req )
throws ServletException, IOException
try
System.out.println("href clicked..");
pgSampleTiledView tiledView = getSampleTile();
System.out.println("\n\n\n\n@@@@@@@@@@@ No of tiles >>>
"+tiledView.getNumTiles());
int n = tiledView.getNumTiles();
for (int i=0; i<n; i++)
tiledView.setTileIndex(i);
System.out.println(i+".
"+tiledView.getTbValue().getValue().toString());
this.forwardTo(req);
catch (Exception ex)
ex.printStackTrace();
2) Tiled view display
I have tiled view inside another tiled view. Based upon the data
retrieved from the database, lets say, the outer tile needs to be
displayed twice and the inner tile 3 times and 1 time.
For Ex: Lets say, the desired output from these tiled views is as
follows
STOCK INVESTMENT
stock name1
stock name2
stock name3
OTHER INVESTMENT
other investment1
The outer tiled view displays the investment type headings (STOCK
INVESTMENT or OTHER INVESTMENT) and inner tile
displays the actual stock names or the other investment names. Both
the tile views are bound to a default model. In the begin display
of these tiled view I'm setting the size of the model as
getPrimaryModel.setSize(requiredsize).
If i display 3 records in the inner tiled view in the first iteration
and i try to display 1 record in the second iteration, it displays 3
records
properly the first time but it doesn't display any records second
time. super.nextTile() returns false right away second time.
But If I try to display 1 record in the first iteration and 3 records in
the second iteration as below, it works fine.
STOCK INVESTMENT
stock name1
OTHER INVESTMENT
other investment1
other investment2
other investment3
Please let me know what could be the problem.
Thanks

Re: [iPlanet-JATO] Re: onBeforeRequest(); Finding requested view from requestContext

If you want to stop a JATO request in its tracks, you have a little black
magic at your disposal: you can throw a CompleteRequestException. This
indicates to the JATO infrastructure that it should immeditately stop
handling the request, but not generate an error, as the develper has taken
full control. You can generally throw this error from anywhere, at any
point--it is a RuntimeException, and is "tunneled" through other exception
handlers where appropriate.
In your scenario, you want to check if the user is logged in, and if not,
save the target URL using the parsePathInfo() method. Then, forward to the
login page and then throw a CompleteRequestException.

It turns out I cannot forward in the onBeforeRequest() as it will
output the viewbean and then continue to process the request which in
turn trys to do a RequestDispatcher().forward after data has been
written to the stream which does not bode well with the servlet
container. Thus, it appears I have no control of the request in the
onBeforeRequest() method. Is this correct?
In light of this new observation I am now going to create a base view
class that all views will extend from and override the

Dynamic Tiled View display question

Hi,
I?ve been working with JATO during this month, i find
the framework very flexible but a bit complex to
undertand.
Currently i?m triying to make the following test, but
i?m in a dead point.
I must create a page that is composed by a form, the
children views of this page that compound the form
must be created on request time, this is because the
displayfields that i must include are included on one
atribute that is included in te request made for the
page that contains the form. Additionally the HTML
representation of each attribute can change from
attribute to attribute (It depends on the type of
attribute that i want to display). I found that
Pagelets can be helpful to decide in request-time the
HTML element to be included. I?m having some trouble
(a conceptual one) in triying to integrate a TiledView
that iterates over an element that can change its
appearance base on the type specified in its own
model.
Someone o you guys faced these problem before, its
possible to have this kind of dynamic features?
Thanks in advance,
Javier Camacho
Developer

OK, I understand your task, and I follow your solution up to the details
of the custom pagelet, but everything sounds correct.
What exactly are you confused about with the beginDisplay event?

Thanks for your interest Craig, i will make some clarifications in
order to give you some answers:
The context of my problem is:
I want to display in a page some Custom Objects relative to my domain
problem, to make it simple lets call these objects MyObjects,
A class MyObject contains 2 variables: "label" and "question_mode".
Depending on the value of "question_mode" (an integer) i must display
in the response page some type of HTML element or another, lets say:
question_mode = 1 -> TextFiled
question_mode = 2 -> ComboBox
question_mode = 3 -> ListBox
But i have another constraint to my problem: the set of MyObjects (the
instances of MyObject) is determined at request time, so i have to
check in the RequestContext for a value, then that value is used to
search in my MetaData to define the set of MyObjects that i must
display.
To put an example:
If the value of my attribute is 1 i must display a set of 5 MyObjects,
and each one with its own "question_mode". So the response page to be
generated for the client its entirely dynamic, no only by the number
of MyObjects to be displayed, the HTML representation for the variable
"question_mode" is decided in request-time too.
Well, to address these interesting question i thinked (inspired by
yoour excellent Sample App) in the following general strategy:
1. I created a Custom Tag for the display MyObjects, the jsp looks
like these:
<jato:useViewBean className="testapp.module1.phase1ViewBean">
<BODY>
<TABLE>
<TR>
<TD ALIGN=left><B>MyObjects:</B></TD>
</TR>
<jato:tiledView name="TiledView1"
type="testapp.module1.MyObjectTiledView">
<testapp:myObject fireDisplayEvents="true"/>
</jato:tiledView>
</TABLE>
</BODY>
</jato:useViewBean>
2. To display these fields i made the class MyObjectTiledView, this
class only contains one View (an instance of
StylizedMyObjectView.class).
StylizedMyObjectView.class is the peer of the <testapp:myObject> tag.
This class implements the interface PageletView so it can be
questioned about the Pagelet to be included in the page
(StylizedMyObjectView choose the pagelet based on the question_mode
variable present in the Model: MyObject class).
But i?m a bit confused in the way that MyObjectTiledView can interact
with the StylizedMyObjectView.class. (i?m triying to figure the
implementation of the beginDisplay() method).
I hope this could clarify your questions.
Is this strategy correct?. I?m a bit lost in the secuence of calls to
address this kind of dynamic page generation.
I will apreciate any help or experience in related problems.
Javier
Javier,
I am not clear exactly what your are attempting to do. I think you
maybe
using some terminology out of place, or maybe I am just not
understanding, so I will ask these questions:
1) You are using a TiledView. Are the number of fields in the tiled
view
dynamic? I am understanding that they are.
2) These fields are of an unknown type at design time. For one
request a
field might be a text box, next request it might be a list box. Is
this
correct?
3) When you talk about attributes, are you talking about the
attributes
of the tags (name, type, value, label, etc.)? This is not clear to
me in
the way that your are describing in this phrase:
"HTML representation of each attribute can change from attribute to
attribute"
4) When you say "type specified in its own model", what do you mean
by
model? A JATO Model class, or a more generic use of the term model?
5) When you say "displayfields that i must include are included on
one atribute that is included in te request", how exactly are the
fiels specified in the attribute, and again, what is your definition
of "attribute" here? I assume you mean request attibute.

Currently i?m triying to make the following test, but

I must create a page that is composed by a form, the
children views of this page that compound the form
must be created on request time, this is because the
displayfields that i must include are included on one
atribute that is included in te request made for the
page that contains the form. Additionally the HTML
representation of each attribute can change from
attribute to attribute (It depends on the type of
attribute that i want to display). I found that
Pagelets can be helpful to decide in request-time the
HTML element to be included. I?m having some trouble
(a conceptual one) in triying to integrate a TiledView
that iterates over an element that can change its
appearance
base on the type specified in its own
model.
Someone o you guys faced these problem before, its
possible to have this kind of dynamic features?

Re: [iPlanet-JATO] Re: Retrieving all Values from a Tiled View

Todd,
Let me try to explain you this time. I have a text field in a TiledViewBean.
When I display the page, the text field
html tag is created with the name="PageDetail.rDetail[0].tbFieldName" say
five times/rows with same name.
The html tags look like this.
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
When the form is submitted, I want to get the text field values using the
method getTbFieldName().getValues() which
returns an array object[]. This is in case where my TiledViewBean is not
bound and it is working fine.
Now in case when my TiledView is bound to a model, it creates the html tags
as follows.
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[1].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[2].tbFieldName" value=""
maxlength=9 size=13>
Now when I say getTbFieldName().getValues() it returns only the first
element values in the object[] and the rest of the
values are null.
May be we need to create a utility method do get these values from
requestContext.

turned off, and it is turned off for the SQL-based models.

Re: [SunONE-JATO] Re: How to use a tiled view without a model

I'm not sure what is different for you now. You still parse the string
and put it into a data structure. Before the data structure was a
vector, in JATO its just a model with a "hidden" data structure (a hash
map).
MVC only really comes into play when you talk about where your write
this code, and where the data structure is being stored. So really, JATO
takes care of half of the MVC'ness of it all (where the data is store).
You just decide where to be the code to populate the model.
Make sense?
Is there something different required of you in JATO in this scenario
that I am not grasping?

The problem I was solving involved a single string, which contained

The string looked like
this:"time|analyst|description|time|analyst|description|..."
In ND, I parsed it apart into it's components (time vector, analyst vector,
description vector), populated the repeated.
With JATO, how would I make a model for something that doesn't have a
database component like this?
I'm pretty new to this MVC thing, so bear with me.

I guess the only thing "weird" (for lack of a better term) about what
you are doing is that your are populating the model on the "display
cycle". Typically, the cycle goes like this:
Request -> populate model -> update data store -> retrieve data to
populate model -> display data
some of the above steps are optional but hopefully you get the point I
am making.
So what you are doing is:
Request -> populate model/display data
If it works for you, then it's not necessarilly wrong. But I would
probably have my model populated before I forwarded to the target
(displaying view bean) or at a minimum, in the begin display event of
the view bean or the tiled view, but not during the iteration of the
tiled view.

Re: [iPlanet-JATO] onBeforeRequest(); Finding requested view from requestContext

The problem is that you don't know what the target view is until it has
been forwarded to.
Think about it... the request handling view bean (or command object) has
the request handler that has the code that will ultimately forward to
another view bean. This is code that you have written. So, until that
forwardTo() is invoked, there is no notion of a "target page".
What you do know is which "page" (view bean) the request is coming from
(the handling view bean or command class). You can get this from the
HttpServletRequest. The attribute name is "viewBean".
So you can get the view bean name by doing the following in onBeforeRequest:
<HttpServletRequest>.getAttribute("viewBean");
But I suspect this is not going to solve your current issue.
You could add the target page name to the page session. If there is more
than one possible target page, it might get a little more involved.
Let me know if the use of page session needs further explanation.

I guess what I am thinking about doing is capturing the requested URL,
i.e. /appname/modulename/RequestName. In the onBeforeRequest(). I
would then check to see if the user is logged in, and if not, set the
URL in the session(or page session of the Login bean) and forward to
the Login viewbean using the viewbean manager. Inside the login view
in the handleSubmit() method I would authenticate the user and then
get the URL out of the session (or pagesession). I would then
magically get the ViewBean/Command object for the URL or otherwise
"forward the request" as if the user had typed in
/appname/modulename/RequestName, which is the behavior I am trying to
acheive.
It turns out I cannot forward in the onBeforeRequest() as it will
output the viewbean and then continue to process the request which in
turn trys to do a RequestDispatcher().forward after data has been
written to the stream which does not bode well with the servlet
container. Thus, it appears I have no control of the request in the
onBeforeRequest() method. Is this correct?
In light of this new observation I am now going to create a base view
class that all views will extend from and override the
onSecurityCheck() method to forward to my login bean. If I can't find
any other way, I will get the URL from the page session and do a
response.sendRedirect() to the URL.
Thanks for the help!

Re: [iPlanet-JATO] Re: using begin childName Display method

Steve,
It sounds like you have your display fields in a container view, and
that container view is inside of a view bean. I haven't tested whether
the fireChildDisplayEvents has a "deep" effect on its container view
children. Meaning that you may have to set fireChildDisplayEvents="true"
for the <jato:containerView> tag instead. If all else fails and you need
to just get it working, you can set the fireDisplayEvents="true" for
each display field tag separately.

Set the size of the model. I know your TiledView is not bound, but actually
it is - to the DefaultModel.
Try this:
getDefaultModel().setSize(1)
getPrimaryModel() should work as well.

The problem in the nextTile() method, the super.nextTile allways
returns false. This seems to be because the
TiledViewBase.getPrimaryModel().next() allways returns false.
All the bound tiled views work fine.
Any help will be appreciated .

I had this issue a while ago and forget the exact solution Todd gave me, so
I'll take a guess untill I can find it somewhere or untill Todd or Mike get
back online to verify.
Set the size of the model. I know your TiledView is not bound, but actually
it is - to the DefaultModel.
Try this:
getDefaultModel().setSize(1)
getPrimaryModel() should work as well.
let me know if that works or not
If I find my example, I'll repost.

Subject: [iPlanet-JATO] TileView not being displayed
Hi All,
I have a TileView which is not bound to any models.
It should display one row however none are being displayed. Following
is the constructor as a reference.
public pgVoucherListrptCheckInfoTiledView(View parent, String name)
super(parent, name);
setMaxDisplayTiles(1);
setPrimaryModel((DatasetModel) getDefaultModel() );
registerChildren();
initialize();
The problem in the nextTile() method, the super.nextTile allways
returns false. This seems to be because the
TiledViewBase.getPrimaryModel().next() allways returns false.
All the bound tiled views work fine.
Any help will be appreciated .

Re: [iPlanet-JATO] using begin childName Display method

Oops. Sorry about that, Craig. I didn't realize I might leave that impression.
I'm sure the tiled
views work since you have so many examples of these and it's a relatively
simple concept, isn't it?
Not to mention a necessary one. I didn't have time to debug my code and find
out what I was doing
wrong where the tiled views are concerned. I decide to just try to implement
tiled views later and
just stick with one of everything for now and get that working.
Yes, I have reviewed your comments and am taking them into consideration. I am
able to save and
retrieve values with my model at this point.
Thanks.

Belinda,
He may also be binding the models, howerver, he needs to change the way
the value appears before it is displayed which is why you would use the
display events.
Your null value issue is a completely different issue and has nothing to
do with it being a tiled view. I don't want anyone getting the idea
that the tiledView binding is broken. It does work. You issue should
have something to do with the inconsistent way in which you are getting
your model. At least from what I could tell in your source code that you
sent me.
Have you reviewed my comments I sent to you in your source code?

Subject: [iPlanet-JATO] using begin<childName>Display method
Content-Transfer-Encoding: 7bit
I want to be able to conditionally show/hide data as well as format
it for display without touching the model. I found the
begin<childName>Display and end<childName>Display methods that
provide the hooks to do this, but I have been unsuccessful in getting
these method to execute. I added the fireChildDisplayEvents="true"
attribute to the jato:useViewBean tag, but this has not helped. I
also added some debug to the ContainerViewBase class in the public
boolean beginChildDisplay(ChildDisplayEvent event) method to see what
was happening. The displayMethodMap was returning null for the child
display methods that were in the view bean. I covered all the bases
(compiling, redeploying, etc.) and nothing has worked. Is there
anything I am missing or is there some working example of this?

The hidden field was present in the page, but it looked like this:
<input type="hidden" name="jato.defaultCommand" value=""../search"">
Seems like there is a small bug in the code generating this tag.
FYI - I am using JATO1.2
What file displays this text? Maybe I can go in and fix it and rejar
it.

To answer your question - it should work as you described. Some of the JatoSample make use of the defaultCommandChild. Can you try
running the sample BasicSample->Field Types and let us know what you
see.

Subject: [iPlanet-JATO] Using the defaultCommandChild in a form
I am trying to set the defaultCommandChild in my jato:form tag to be
the searcg button. The search button definition is:
<jato:button name="search"/>.
The form tag definition is:
<jato:form name="PendingIA" defaultCommandChild="/search">
Clicking on the search button works fine, but hitting return in one
of the textFields (which submits the form) passes a value of "" to
the createChild method in my viewBean, which throws an error. Why
does this not just work as normal and trigger the handleSearchRequest

You are using BeanAdapterModel. Unless you've elected to place your BeanAdapterModel instance in the session, it is request-scoped like all JATO objects. This means that on the second request, a new model is created, and unless you set the list of beans on the model, it has no beans on which to set the incoming data.
An easy place to set the list of beans is in the constructor of the model. If, however, the beans are in one of the J2EE scopes (either already, or because you elected to put them there sometime earlier in your request handling), then you can use the model's ability to look up the beans in that scope by adjusting the Bean Scope and Bean Scope Attribute properties.

Getting the Values from a Tiled View

Hi,
I have a TiledView and I have checkbox in the tiled view. I am trying
to get the values of the checked boxes.
I have coded like this.
Object[] links = getRSystemLinks().getCbSystemUrl().getValues();
if I see the links.length i get only one. In html If I see the code
it appends the TileIndex in brackets. If I replace the TileIndex with
0 in all the fields in endCbSystemUrl method I get the correct values.
In the TiledView beginDisplay() method my code is like this.
if (getPrimaryModel() == null) throw new ModelControlException
("Primary model is null");
super.beginDisplay();
resetTileIndex();
pgCustomizeLinksViewBean parentBean = (pgCustomizeLinksViewBean)
getParent();
((DatasetModel) getDefaultModel()).setSize
(parentBean.SystemChoicesValue.size());
Any Suggestions on this.
Thanks
Namburi

Namburi--
Remember, the getValues() method does not return the values from a column in
a TiledView. It is strictly for use by fields that can have multiple
values, like multi-select list boxes.
DO NOT remove the indexing feature from the field names, especially in the
case of checkboxes, because checkboxes aren't submitted back to the server
unless they are checked. By overriding the automatic checkbox tracking
feature JATO provides, you won't be able to tell which checkboxes were
actually checked by row--you'll simply get back a list the same size as the
number of checkboxes that were checked, without any placeholders for the
ones that weren't checked.
Instead, on submit, you simply need to move through the tiledView and check
the value of checkbox on each row:
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
You can use the same construct to build up an array or list:
List checkedList=new LinkedList();
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
checkedList.add(new Boolean(true))
else
checkedList.add(new Boolean(false))
