Brian - thanks for the update.
I've taken quite a bit of heat from above for having selected myeclipse over netbeans since this issue came up, so good to know it's being worked on.
I managed to keep my job, but it really has been that serious a problem...

I've been coming here manually, never got an email notice of any replies on this thread, despite having checked the 'notify' box below.

Perhaps you & I are missing notifications due to something in the forum system ....

I have some good news on this front. In MyEclipse 8.5M2, we did manage to put some improvements in, these do not fix Matisse for the use case we reproduced internally, but may improve performance in some of your use cases, which may be different. If you could try 8.5m2 and let us know, that would help. Note that the standalone modules will not be updated until 8.5GA, so you need to try in a full MyEclipse install.

Earlier today, we managed to put in a fix for the problem we reproduced locally, however, this will not be available until 8.5GA due in about a month. Over the weekend I will work on getting a small update to you guys (which you can install on top of 8.5M2) and you should be able to tell us whether it fixes your problems too.

Again, sorry for the significant inconvenience caused (esp scooternh), but we hope we have it nailed now.

Given the high priority of this issue, we worked hard on making a fix available for immediate use. If any of you could try it and give us some feedback, that will help ensure that the issue is well and truly fixed for 8.5.

To install the new plugin in MyEclipse 8, do the following:
1) Go to Help > Manage MyEclipse Plug-ins.
2) From the list that shows up, choose the MyEclipse Visual Swing Designer and select Uninstall.
3) Restart MyEclipse as requested, go to Help > About > Installation Details > Plugins and sort by plugin Id. Ensure that there is no plugin with Id com.genuitec.eclipse.dehory in that list, confirming that the plugin has been uninstalled.
4) Download this file and unzip it into the dropins folder in your MyEclipse 8 installation directory. Your dropins folder should now have a file named com.genuitec.eclipse.dehory_8.4.200.me201002221244.jar
5) Start MyEclipse, go the the location mentioned in step 3 and ensure you see a com.genuitec.eclipse.dehory plugin with the Id 8.4.200.me201002221244
You are now running with the new version of the fixed plugin and should not experience the lockup anymore.

To install the new plugin in MyEclipse 8.5
1) Go to Help > MyEclipse Configuration Center
2) From the Dashboard tab, deselect MyEclipse Visual Swing Designer
Follow steps 3-5 from previous section.

Since this is a temporary / testing fix, this could cause issues when upgrading to 8.5 GA; before upgrading, simply shut down MyEclipse, delete the JAR file you unzipped into the dropins folder and restart MyEclipse before attempting to apply the update.

Please let us know if this works and fixes the lockup issue for you.

Hi Brian,

I uninstalled the previous version, then unzipped the provided file into dropins. After restarting the plugin is not visible. I also attempted the same thing using the plugins folder, but that did not work either. Perhaps my problem is that I am using a classic install with stand alone modules. Is it possible to get the patch to work in this configuration?

Thanks,
Ron

Ron,

Sorry, this fix is only for MyEclipse 8 or 8.5M2, it won't work with standalone modules as it expects some other MyEclipse plugins to be present. The standalone modules will only be updated in 8.5 GA.
Would it be possible for you to try with MyEclipse?

Any news on this? I'm currently evaluating switching to MyEclipse for Matisse form design and one of our forms locks up, both under Eclipse 3.3.2 with the Matisse plugin, and using the latest version of the full MyEclipse desktop environment.
A possibly interesting clue is that it's the only form that had been reworked in NetBeans 6 to use GridBagLayout managers; all other forms use the FreeDesign layout manager and open fine.
Is there any information I could send that might help troubleshooting? Thanks!

One more update -- I manually substituted GridBagLayout references with BorderLayout references, and the form opens. Of course, the layout is all messed up, but I've started switching back to GridBagLayout and the form still reopens so far.
