GridLayout Problems after Juno SP2 Update [message #1041906]

Hi @all,

I'm using SWT Designer Version: 1.5.2 Build id: 2013.03.07 (Build from January has the same problem!) and different Juno installations.
To make short what took me some hours Confused

->
I use a workspace with Juno Java EE IDE 1.5.1.20121004-1506 and the above version of WindowsBuilder. I open my workspace and a JFace Application window with the designer - it shows up like in BeforeJunoSP2.jpg.

I copied the complete juno installation and updated to 1.5.2.20130211-1820. No other plugin is updated! When I open the same Workspace and java class like before, it shows up like in AftfterJunoSP2.jpg.

Of course I also tried starting the updated juno with -clean, but that didn't help.

When I run my program the layout is correct !

Any ideas ? Is this a bug or do I need to update/delete .. something else ?

Thanx
Thomas

WIthout a test case, I can't even guess what the problem might be.

Hi Eric,

long time no hear Smile

Here is the testcase. Simply load the project with Juno 4.2 SP1 and then with Juno 4.2 SP2 and the latest WB version from the market. You will see the affect thats also shown in my sreenshots. It seems that the parsing starts with the last element in the grid an places it in the first cell.

Pls. let me know if you need further info.

I can confirm this error.
In my UI-files this strange behaviour also occurs. There is no difference between Gridlayout with 1 column and >1 rows, >1 columns and 1 row, or a layout with many columns and rows.
At runtime everything is okay.
I'm also on the latest WindowBuilder and Eclipse 4.2.2

Same here. We are struggling with this. The updated version 1.5.2 is not working on Juno SR2.

What OS are you using?

We tried Eclipse 4.2.2 and the latest WB under OSX and it looked fine.

If you are seeing a regression solely based on the Eclipse version used, then there must be a regression in that version of Eclipse. We just don't know what it might be. It may even be OS-specific if you are using something other than OSX like we are.

I'm using Windows 7 64-bit.

If it was just an eclipse glitch I wonder why the layout is fine when I start my application (directly in eclipse). Too bad you can't reproduce the problem but as you can see in here I'm not the only one.
What I also found in the forum was that the problems seems to go away using eclipse 4.2.2 with the old version of WB (5.1.0). I cannot confirm this - I tried 5.1.0 too but the problem persists.

Thx to Eric Clayberg (See http://www.eclipse.org/forums/index.php/t/468284/), the installation worked. I had to manually download the JAR and install it (locally as an archive throught the "install new software..." option)

Use this link: http://www.eclipse.org/windowbuilder/download.php

Do NOT use this one:developers.google.com/java-dev-tools/download-wbpro

Hi Frederic,

thanks for this link. I uninstalled WB and installed it from the updatesite behind your link.
Unfortunately the layout doesn't work with this version either. Furthermore - this is exactly the version that I use under eclipse 4.2 SR1 - there it works perfectly.

@Eric Clayberg

are there any suggestions what I could try/do now?
Everything I tried failed and showed the widgets in the provided Testcase in the wrong order. I uninstalled and installed different versions from different download links. Neither of 5.0, 5.1 and 5.2 are working with Eclipse SR2 on windows 7 which is rather annoying.
Could you manage to reproduce the problem on a Windows 7 system ?

thanks and br
Thomas

We can reproduce it under Windows but not OSX. It appears to be an issue with CTabFolders rather than GridLayout and caused by some recent change to SWT (in Juno SP2). Other layouts like FillLayout are similarly affected when contained within a CTabFolder. Nothing in this area of WB has changed in quite awhile, so we have not been able to identify the underlying issue.

Do you see this happen anywhere outside the context of a CTabFolder? if so, please send us an additional test case. If not, we will focus on recent changes made to CTabFolder that might cause this.

I checked a couple of classes in my project. All problems are connected to CTabFolders but not all CTabFolders have this problem ! Some are completely OK some only affect one subwidget. For example there is a CTabItem/composite with Formlayout containing 7 Groups with GridLayout. Only one of these groups gets destroyed (=parsed in the wrong direction). Every time the code gets parsed again (returning from another CTabItem) the layout gets worse.

As I wrote before it seems to be "just" a designtime problem. When I start the program within eclipse using the new SWT and JFace classes and runtime all layouts are fine.
