JDeveloper Hangs in JSPX design mode

hi,
I have been working with a project in JDeveloper (ADF Faces) the last six months and things have been going fine. Now that we are only a few weeks from release we are suddenly getting performance problems and the IDE hangs on certain jspx pages when we try to show them in Designer Mode. Our version is 11g (11.1.1.0.0).
We get the following IDE exception:
SEVERE: lock starvation; thread 'status-0' blocked on lock 'orderclosure.jspx' for more than 20,000ms:
+"status-0" id=58, blocked, no reads, no writes, no history collected:+

+     at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907)+

We need to solve this fast, can anyone give us some pointers.
Thanks
Stephen

The problem is odd, I check the Task manager when I try to open the page. I get some CPU spikes but nothing major, and memory looks okay, over 1.5G available. This odd thing is that this is particular to certain JSPX pages we have written. Some load fast and some load slow/hang. I have check the JSPX and the Binding and I can see any common factors. It feels like JDev tries to get access to something during the setup of the designer for the page but is blocked? On some pages we are waiting 4-5 minutes for the designed to show the page.
I don't think the pages are very larger (what is large?), I mean we have a good number of components particularly Panel Groups etc.. As an example one of our pages which takes time has the following, 2 tables, 2 select many, 2 Box Layout, 3 buttons, 1 text field. 3-5 minutes to load.
Thanks for your help.

ADF FACES: jdeveloper hangs on opening a .jspx file

I may not have had this file open since updating to EA13, but I'm not positive. Upon trying to open the file (code below), jdeveloper hangs. It sucks down roughly 50% of the CPU and the memory footprint slowly grows (about 3 MB per minute). As of now, I've tried restarting jdeveloper and then opening the file, but the behavior is the same. I have let it run for nearly 15 minutes and it is still hung (to the point that the display is not redrawn when a window, such as the task manager, is closed after obscuring part of the jdeveloper window).
I'm running jdev version 10.1.3.0.2.223

Helo there,
I am having exactly the same problem, everytime I include af:forEach tag inside the af:selectOneChoice for example, preview of JSP is not shown and whole developer hangs, in task manager I can see 100% CPU occupation by JDeveloper.
But the code itself is ok, if I run the page while editor is in Source mode Page is properly shown in browser, but when I change editor mode to Design it hangs.
I am using Faces EA17 and JDeveloper 10.1.3
Does anybody else face the same issue?

JDeveloper shutting down when invoking design mode

I use JDeveloper version 3.2.2 and Oracle version 8.1.7, and Windows 2000.
Very often when I try to open a form in design mode, JDeveloper shuts down, after displaying "Opening <form>" in the structure pane. This gets very frustrating at times, when you feel that your tool is working against you. I must add that the actual project is rebuilded (with no errors) and saved before trying to open the form in design mode. I believe this is a rather frequent error in JDeveloper.

I hasten to add that my PC is an IBM 300 PL - 600MHz/PIII, 256MB RAM.

Jdeveloper 3.1 freezing when moving to design mode

Greetings all,
I have created a Panel with the Business component data forms wizard. I have chosen a table and have completed the wizards steps.
When I go to view the generated class (Panel) in design mode jdeveloper freezes.
Thank you in advance for your attention and help.
John.

Brian,
Thank you for your attention.
This are the answers your questions.
1. JDeveloper
3.1 Build 681
IDE 3.1.681
JBO 3.1.681
DAC 3.1.681
OJVM 1.3.0
COMMON 3.1.230
2. Both ways produce the same result when trying to move to the design mode.
3. No output to log - JDeveloper freezes
4. Only 7.3.4 (tested against two instances)
Note: This maybe of great help. When I was reviewing the entity object (the table which on the panel) I select the Validation tab and JDeveloper was frozen.
I reviewed the documentation and found this information.
"Business Components for Java provides a framework for defining, implementing, and executing validation logic in middle-tier components." Is JDeveloper looking for something to do with this validation tab which is causing it to appear frozen?
I would like to resolve this problem as soon as I can. I would like to explore JDevelopers functions instead of having to code all GUI elements by hand.
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by JDev Team (Brian):
John --
Thanks for your help in resolving this issue. I have a couple of follow up questions for you so that we can nail this down:
1. Which version of JDeveloper are you using?
2. Are the panels created with the Dataform wizard, or did you add the components by hand? If you have only been using one of these methods to create your form (for example, the wizard), could you try the other method, and let us know if you experience the same problem.
3. Please send us the output from the logging window: edit [JDeveloper_home]\bin\jdeveloper.ini and set LogConsole=1 and edit [JDeveloper_home]\lib\jdeveloper.properties and set jdeveloper.logOutput=- and restart JDeveloper.
4. If you have another database version available, could you see if you have the same problem there.
Thanks for your patience!

[BUG] Design mode failure

Hello,
Although enhanced, the design mode in JDeveloper 11g can still fails under some circumstances. Namely, it happens when the skin contains some absolute dimensions. Here's a simple test case. Of course, the page structure looks odd, but it was stripped from other relevant element to isolate the design mode failure source.

Design mode not working in Jdev 10g

Hi All
I am facing some problem in Jdeveloper 10g. I created a project few days back. Today when I am opening jsp pages of that project, It is not coming in the Design mode. It writes only "Page Directives" instead of showing Forms and Tables. But when I run them, it shows the tables etc properly in browser.
Can anybode help me out to open the page in Design mode again.
Regards
Rexy

Hi Chris
According to the note, These files gate changed when they are inside WEB-INF. But in my case, these files are parallel to WEB-INF and still they are showing this kind of behaviour.

Bug: HTML table row with id on design mode does not display properly

JDeveloper studio edition version 10.1.3.3.0.4157
Created a very simple JSP file, which has a table of 3 rows, 3 columns.
Added id attr to second row, JDeveloper does not recognize the row in Design mode. See sample code below.
<html>
<head>
<title>JDeveloper JSP Design Mode tr with ID</title>
</head>
<body>
<table cellspacing="0" cellpadding="5" border="1" width="300">
<tr><td>1</td><td>2</td><td>3</td></tr>
<tr id="row2"><td>4</td><td>5</td><td>6</td></tr>
<tr><td>7</td><td>8</td><td>9</td></tr>
</table>
</body>

Thanks for your quick response.
I will post another bug. Please check.
thanks!

Did you add the swing library to the list of libraries used by the project? (double click on the .jpr file in the upper navigator window, click on the library tab)
Is swing 1.1.1 there? If you, add it via the Add button.

Can't switch to design mode! bug?

I created the following code as:
-created a new class
-dropped a SessionInfo on it
-set up the connection and appmodule for the sessionInfo1
-dropped a LoginDlg on it
-set up the dataItemName to the sessionInfo1 for this loginDlg1.
I quited the JDev3.1
I started JDev3.1 and tried to switch to design mode -> nothing in the navigator!
I quited JDev3.1
I started JDev3.1
I commented the line setting up the loginDlg1 dataitemname (the last line)
I can switch to design mode now!
You have to restart the JDeveloper not only comment out this line, to be able to design!

loginDlg1.setDataItemName("infobus:/oracle/sessionInfo1");
Tib.
Ps.: If I drop a LOV control on the Class, and I would like to design this as well, then both the loginDlg.setDataItemName, and lOV1.setDataItemName lines must be commented out!

You're lucky. When this type of thing happens to me, JDeveloper 3.1 crashes. I've found that by deleting random sections of code, eventually it can open up again.

Producing HTML wireframe in JDeveloper using Visual Web Designer

Using 10.1.3.5 on winXP..
You'd think something as simple as an html wireframe could be easily accomplished using the visual editor... doesn't work at all. I create an html template, then create an html page from template... fine so far.
As soon as I try to insert a component from component palette in Design mode... it doesn't let me... there are no valid insertion points anywhere... all I want is to produce some quick screen mockups, basic wireframe for clients to test out and review.
Has anyone ever done this with Jdeveloper successfully?

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

Can't select anything in design mode

I am new on a large Flex project, and when I go into design mode on one of the mxml files, I can't select anything. The other views work fine. Is there a lock, or something? Below is what it looks like (black mark just hides brand info). Note that there is a red line near the bottom. It is actually selectable, but it doesn't do anything. If I go to Source mode and select a chunk of code, then back to design mode, it does show it as selected.
This in Flex Builder 3, thanks.

Have you tried using the outline view for selection?

Dreamweaver 8: Java script in Design Mode

Mac OS 10.4.11 Dreamweaver 8
I have a web page with a java script that displays a random picture from a list of images each time you reload the page.
http://www.irises.org
It renders fine when viewed in a browser, but the image does not display when viewed in Dreamweaver Design mode. The random image does not display and lacking the image other things are out of place.
The script that sets up the image array:

The code (further down the page after the all the list elements) that generates the image:
           <SCRIPT LANGUAGE="JavaScript">



</script>
Is there a way to get it to display correctly in the Design mode?
Thanks
<br />
</script>

Is there a way to get it to display correctly in the Design mode?
I don't think so, at least not with this script. What you need is for an image to be displayed on the page by default, and for the javascript to only change the src attribute's value. Something like this -
At the point where you want the image have -
<img src="the_path_to_some_default_image.jpg" id="rotation" />
and in the javascript, change this -
document.write('<img src="'+theImages[whichImage]+'">');
to this -
document.getElementById('rotation').src='theImages[whichImage]';
See if that works....

Flash IDE Components in Flex 3 Design Mode. Can they be visible there?

Hi,
Im exploring Flex to get a grasp on its concepts and am currently looking into building components in the Flash IDE. Though i guess its likely that when you're more familiar with Flex you build your components in Flex, like said Im exploring its concepts and like to know where and how the Flash IDE fits in its workflow.
I made a simple Flex Component in the Flex IDE, which shows up fine when I run the Flex project. But it does not show in Flex Design Mode.
I have exported the component from Flash as an SWC and added the SWC to the Flex library path. The symbol in the Flash IDE extends UIMovieClip. Now I read in 'Using Adobe FlexBuilder 3' (p.67) that the Flex Components panel only lists visible components, according to the documentation 'components that extend UIComponent'.
Note that my question is about being visible on the stage in Design Mode, not in the component panel. As UIMovieClip doesnt inherit from UIComponent (and the UIComponent class doesnt seem to be available in the Flash IDE), is this also the cause that the Flash IDE component is not visible on the Flex stage in Design Mode?
Can someone confirm, or deny this?
Regards,
Marcel

Hi Latha,
thanks for your feedback. Reading it back though, Im still not sure whether Flex components build in the Flash IDE (using the Flex Component Kit for Flash CS3) can be visible in Flex 3 Design Mode.Maybe you can be a bit more specific and save a lot of Flex beginners a lot of headaches.
I understand that MXML components can be used in Design Mode. I also understand that if your component is AS you have to create a Library and link that to your project to make them visible in Design Mode. I also understand that Flash Builder 4 does "support rendering of UIMovieClip objects which are in library (swc) and added to the project build path"
This actually doesnt answer my question really. Does this mean there is no way to render Flex components build in the Flash IDE (using the Flex Component Kit for Flash CS3) in Flex 3 Design Mode?
Regards,
Marcel

GIF won't play in design mode, but previews fine... any ideas?

My animated gif loops in browser preview, but only plays on the stage when i move it around. If I leave it selected without moving, it sits there frozen. Any ideas why my gif won't play properly in design mode? Thanks!

Thank you for confirmation that that is how things should work. I'm new to
the program and following some Lynda tutorials to get up to speed. My most
recent lesson included the gif in exercise files, and everything seems to
function both in Photoshop and the browser. Even in edge design mode, if I
press on the gif and move it around, it plays and loops fine. But as soon
as I stop moving the gif, it returns to first frame and stays stuck there.
Whether selected or not, it just sits there frozen. If I switch
applications and come back to edge, I catch a glimpse of other frames, as
if the gif was playing in the background. But then it stops again, kind of
like a watched pot The behavior seemed glitchy to me, but I thought I
might be missing a setting somewhere. I'll try with other gifs, I guess..
Thanks again!
