Number of states vs more .mxml files

I am trying th figure out the best approach. After login I change states and have a menu that can do is 7 different direction based on selection.
What is the advantage/disadvantage of changing the state of the current .mxml file verses having 7 different mxml files?
Thanks,
Pete

Right now I am developing an application and I have my main application with the following components.
AppHeader
AppFooter
AppContent
Then the AppContent MXML file contains many states for the different menus, around 7.
These states show one at a time using a TabNavigator to display the content is the one section of the screen.
One of the states has another set of nested components
Right now I am having a VERY difficult time getting information into my database. I think it is because of the number of states and components. I am coming to believe that you have to be at the application mxml file to send information but I could be wrong. The only problem with components and state nesting is that it can get out of control quickly. It might better to refactor the application. I plan on doing this after the initial assessment from my managers.

Declaring skin states in an MXML component?

From the docs, you can declare skin states in a .as file before the class declaration, like this:
[SkinState("up")]
[SkinState("over")]
[SkinState("down")]
[SkinState("disabled")]
public class Button extends Component { .. }
But how do declare states in a .mxml file? There is no "public class ..." statement to precede.

So maybe this isn't possible? I have had such a hard time finding docs on the component side of the skinning contract.

Not able to get the data from variables contained in more than 1 mxml file

I have got 5 Bindable Public integer variables in total in 5 mxml files (Pages). Each variable is assigned it's value in a Public function in each of the mxml files.
What I need to do is add up the values of the 5 variables. The way I approached this was to create a public function add5Variable in my main mxml file (Page1) as shown below.
[Bindable]
public var varTotal:int = 0;
public
varTotal = (variableP1 +
Page2.variableP2 + Page3.variableP3 + Page4.variableP4 + Page5.variableP5);
return(varTotal);
I have got a TextInput field on Page5 where I display the varTotal. The function add5Variable is called when moving from Page to Page.
The results I am getting is that the varTotal will always be the value of variableP1. When I tried some debugging in Flex Builder it showed me that the other 4 variables had a value of 0.
Why is this the case and do you have any suggestions on how I can get the correct total for varTotal?
Thanks
function add5Variable():int {

The code below looks correct. Is that the expected behavior of your app?

Eclipse +flex 3 plugin crashes when trying to see mxml file in design mode

Hi,
I have strange problem I've been struggling with for 3 days.
I have eclipse-jee-europa-fall2-win32(eclipse europa 3.3.1.1)
+ adobe flex 3 eclipse plugin.
My workspace consists of several projects + one library.
There is not problem when trying to edit any mxml file when
my library is not imported yet. Once I import it to my workspace I
cannot see any mxml file in design mode since it crashes with the
following msg in log:
Did anyone have similar problem and maybe knows the
solutiuon? I've reinstalled/redownoaded eclipse, flex plugin, flash
players and so on. What's more it happens only on my machine - same
project on different one works without crushing.

I've found solution by myself so I'll present it here. Maybe
someone will need it.
The problem of such behaviour was that Flex plugin always (at
least on my pc) wants to ustart eclipse using its own JRE from here
C:\Program Files\Adobe\Flex Builder 3 Plug-in\jre (default dir).
This environment is Java 5. When you go to
eclipse>window>preferences>Java>Installed JREs and you
delete default Flex JRE, add new to point to for example C:\Program
Files\Java\jre1.6.0_04 eclipse still uses JRE from C:\Program
Files\Adobe\Flex Builder 3 Plug-in\jre. Do not know why
Flex/eclipse does that but if you simply overwrite C:\Program
Files\Adobe\Flex Builder 3 Plug-in\jre files with newer JRE from
C:\Program Files\Java\jre1.6.0_04 all works perfectly.
Hope it helps somebody ;-)
thanks Artur

Implement forms in different .mxml files

Hi!
I'm starting developing an application with Flex wich will
have differente views. I wonder if it is possible to implement each
view in a different .mxml file and how to do it. I now it is
possible to define states but what I want is to define different
forms (that probably would have states).
Any help will be appreciated.
Thank you.

Yes, you can create separate .mxml files for just about
anything. So you could create a new .mxml for each "form" view
where <mx:Form> is the root of each file.
States apply only to the file they are defined in, so you can
have a form with different states based on form item selection. I
can then nest components with states within on another.
Also, as Greg points out, "States" are not used for
navigation, that is what the navigator containers are for. (i.e.
ViewStack, TabNavigator, etc...) States are for modifying a
component slightly based on an event.
Using your example, if a user selects a specific option in a
ComboBox, you add another TextInput to the form. In a more generic
example, you display a catalog of products. When the user mouses
over a product, the image is highlighted and an add to cart button
appears.

Passing parameters between mxml files(used in viewstack).

Hi All,

   I'm having following questions:
   How to keep username in session scope. Need to be accessed in all pages.
   How to pass username from login page to home page.
   In HOME page, if I mention 'creationComplete="ro_records.getinquires()"' it will be invoked when I call login.mxml file, so how to invoke getinquires() method passing username when login is successful.
   Thanks in advance.
Regards,
Sharath.

If this post answered your question or helped, please mark it as such.
To keep username in session scope, so it can be accessed in all pages, and to pass the user name from login to home page, you use custom events, as in my example application. The Flex project archive is attached, but here is the code:
-------------- assets\css\appHeader.css -----------------
/* CSS file */
.welcomeLabel{
fontSize: 20;
color: #FFFFFF;
left: 50;
verticalCenter: 0;
.titleLabel{
horizontalCenter: 0;
verticalCenter: 0;
fontSize: 24;
.loginButton{
right: 30;
verticalCenter: 0;

In SQL Trace how to see which statement getting more time .

Hi Expart,
In SQL Trace (T-code ST05) . I am running the standard transaction . how to see which statement
running more time and less time . suppose one statement running more time so how resolve the
performance .
Plz. reply me
Regards
Razz

> The ones in 'RED' color are the statement which are taking a lot of time and you need to

No, that is incorrect, the red ones show only the ones which need several hundret milliseconds in one execution. This can even be correct for hard tasks. And there are lots of problem, which you will not see
I have said everything here:
SQL trace:
/people/siegfried.boes/blog/2007/09/05/the-sql-trace-st05-150-quick-and-easy
Go to 'Tracelist' -> Summarize by SQL statements', this is the view which you want to see!
I summarizes all executions of the same statement.
There are even the checks explained, the slow ones are the one which need a lot of time per record!
See MinTime/Rec > 10.000 microseconds.
Check all number of records, executions, buffer, identicals.
The SE30 Tipps and Tricks will not help much.

It turned out that my Captivate file exceeded 50MB (the
working “.cp” file) and this causes problems when
outputting, they tell me at Captivate support, that weird
corruptions happen. I tried removing the audio from the Flash after
synchronizing the audio to screen activity, then saving a non-audio
version, then importing it into Captivate, then importing the audio
into Captivate. Make sure to check Options/Synchronize to project
when you import the .swf. That solved the problem for me. Good
luck!

For any given session, you can then drill down for more detail. You can further customize the information you display by specifying manual or automatic data refresh, the rate of automatic refresh.
In addition to these useful monitoring capabilities, OSM allows you to send LAN pop-up message to users of Oracle sessions.
Features:
--Capture all SQL statement text and archive to files in real time
--Pinpoints problematic database sessions and displays detailed performance and resource consumption data.
--Dynamically list sessions holding locks and other sessions who are waiting for.
--Support to kill several selected sessions
--Send LAN pop-up message to users of Oracle sessions
--Gives hit/miss ratio for library cache,dictionary cache and buffer cache periodically,helps to tune memory

Hi All

statement1 (takes 2 mins)

Can anybody tell me if this is correct behavior or am I missing something here ?Calling procedure must terminate before data is actually written to the file.
It is expected & correct behavior.

Change a state in main.mxml from a script in another mxml

Hi,
i'm having some trouble with my application, let's say i have the main application file called MAIN.MXML
in wich i have set different States, and have different forms.
now i have a form called loginForm which contains the textInput item for Login and Password, i also have a link Need to Register
which onClick will change the state to show in the same panel a different form registerForm (with the relevant textInput items)
now the MAIN.MXML includes a custom component called <comp: NetworkManager /> which includes all the logic scripts and MXML
tags to create and manage an HTTPService request to a PHP Server.
when the user click on the Login button, this will call a function included in the main.as script (imported in MAIN.MXML) which
will call a function in the script within NetworkManager.MXML passing all the form data.
in NetworkManager.MXML the script will create an XML message, will send to the PHP Server and wait the response... if this comes
true the user is authenticated, otherwise is not.
so far so good, i get the message sent, the correct response back. Now i want to hide the form in MAIN.MXML and put something like
Welcome firstName lastName!! instead. But i don't know how to do it. If i try to access the states in MAIN.MXML from the NetworkManager.MXML
i'll get all sort of errors which i don't have it here with me.
I know this sounds like a newbie question, and it really is ... any taker?
your help is much appreciated.
thanks

who is the caller of loginForm then? i've tried with Application.application.loginForm but i do get the same error though.
loginForm is contained in a Canvas item, is it the caller? or who else?

How to include components into mxml file?

I have an mxml file with multiple states and it is getting
quite large. I would like to divide these states into their own
components. How can i include these into the mxml file?
Thanks!

I couldn't be happier that you asked this question and if you
don't mind I'd like to extend on it a touch since it directly
relates to my topic.
I am right with Dr. Goomba (Great name) when it comes to
filesize of a single application.
The flash player has always been a big proponent of small
file size and fast dowloads to ensure our users have a pleasant
experience in our applications. I have been going through the
documentation tirelessly and the only mention I really see as a
supporter of that theory is "RSL" documentation which, believe it
or not, actually advises against them unless you are using them
across multiple apps.
So, my question is a tack on to Dr. Goomba (Answer his first,
this is just a supporter):
Has Flex 2 moved us away from fast delivery? I have an
application already up to 300k that could easily reach the 700k
range (I think, based on my total progress so far) - It doesn't
seem to me that the focus is still on loading things in parts like
the MX 2004 RIA days.

Why must the number of states on all pages be equal?

Hi,
I'm building a complete interactive website in Fireworks CS5 using Master Pages, States and Behaviors for some neat interactivity on the mockup.
My question is why must the number of states be equal on all pages? I have a Master Page with a simple rollover effect on all the links, but on the Profile page I have a popup where you can insert tags. To create an interactive popup on the Profile page I need a couple of states for that popup on the Profile page. As soon as I add more states to the Profile page it loses the content from the Master Page, even if I tell all the layers in the Master page to "share on all states", when forcing the Profile page get's disconnected from the Master page.
There has to be a simpler way of doing this!
Thanks!

There is no way of doing what you want in Fireworks. It's not an HTML editor and can't generate more than rudimentary interactive objects. To create more sophisticated interactive objects you need have some knowledge of coding and use software like Dreamweaver or Flash.

Maximum number of events per audit log file must be greater than 0.

BOE-XI (R2)
Windows Server 2003
Running AUDIT features on all services.
Report Application Server (RAS) keeps giving the following error in the Windows Application Event Log.
Maximum number of events per audit log file must be greater than 0. Defaulting to 500.
I am assuming that this is because the RAS is not being used by anyone at this time - and there is nothing in the local-audit-log to be copied to the AUDIT database.
Is there any way to suppress this error...?
Thanks in advance for the advice!

A couple more reboots after applying service pack 3 seemed to fix the issue.
Also had to go to IIS and set the BusinessObjects and CrystalEnterprise11 web sites to use ASP .NET 1.1 instead of 2.

IMP-00008: unrecognized statement in the export file, oracle 11gr2 on redhat 5

I am using Oracle 11g R2 on Radhat 5 linux to import(imp) a dmp file with a table with blob data type. I got the following errors with binary non-ascii on the screen and failed imp at that table:
IMP-00008: unrecognized statement in the export file: (a lot of non-ascii characters followed)
How do that happen and how do we handle it?
-Henry

Hello,
IMP-00008 may due to several reasons.
The Dump may be corrupted, you may also hit a Bug and so on, ...
Is it the only error you got or do you have other error message (for instance IMP-00032) ?
Else, I don't know why you use EXP/IMP in 11.2, the Original Export/Import is not recommended. You should use DATAPUMP which is much more powerful.
Please, find enclosed a link about DATAPUMP:
http://www.oracle-base.com/articles/10g/oracle-data-pump-10g.php
Hope this help.

@John - no luck on the plugin angle. In checking both JDev installs that previously had the problems, they have the default extensions.
@Dave - at the time I can't say we noticed any migration notices, we certainly didn't see the migration dialog though. However the application in SVN was built on the same version of JDev so I don't expect a migration to find any changes anyhow.
However on your second point we always check out into an empty directory, as we're checking out the whole application. As such if as you say the migration utilities is always called, shouldn't that mean we always see the projects modified? We certainly don't, we're on a day by day basis checking out whole applications to different directories and we don't see that behaviour.
In turn reconsidering the modified .jpr file, from what I saw it looks to me that the whole project file is re-set to it's original state. Initially the problem detected was the libraries attached to the project were gone so we couldn't compile, but in close inspection it seems the whole .jpr file has been modified to a rather vanilla setup.
One thing I can say when we originally experienced the problem (and from memory this was true in the dim dark past when it also occurred another time), is it was a check out from a SVN tags directory, not the trunk. In thinking about it, it may be the first check out from the tags directory that we see the issue. However to get around the issue we just revert the project file in the tags directory, we don't actually change the SVN repository code (ie. commit), so the issue should keep occurring. Yet at the moment if we check out the same tags directory, the issue doesn't occur?
Hmmm?
Btw Dave, are you an Oracle employee?
