Build: 3.2 M5 I got a weird situation today in the Package Explorer after opening my workspace. I recorded a screen capture with a demo version of BB FlashBack and will attach it. It seems like the Package Explorer has the wrong elements (maybe working copies?). Java source files inside source folders are opened in the wrong editor (the one for external files). All IResource specific actions seems to be missing. I discoverd this while investigating bug 128761.
Created attachment 35055 [details] Flash screen cast of the Package Explorer
After restarting Eclipse the Package Explorer returned to normal.
anything in .log?
No. There is only an entry that was logged _after_ the restart. I don't think that's related to it. !ENTRY org.eclipse.jdt.core 4 4 2006-02-21 10:13:16.659 !MESSAGE JavaBuilder handling CoreException while building: net.sourceforge.eclipseccase.ui !STACK 1 org.eclipse.core.internal.resources.ResourceException: Resource /net.sourceforge.eclipseccase is not open. at org.eclipse.core.internal.resources.Project.checkAccessible(Project.java:141) at org.eclipse.core.internal.resources.Project.getDescription(Project.java:383) at org.eclipse.jdt.internal.core.builder.JavaBuilder.hasJavaBuilder(JavaBuilder.java:464) at org.eclipse.jdt.internal.core.builder.JavaBuilder.isWorthBuilding(JavaBuilder.java:594) at org.eclipse.jdt.internal.core.builder.JavaBuilder.build(JavaBuilder.java:135) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:593) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:168) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:202) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:231) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:234) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:253) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:282) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:143) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:204) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58) !SUBENTRY 1 org.eclipse.core.resources 4 372 2006-02-21 10:13:16.659 !MESSAGE Resource /net.sourceforge.eclipseccase is not open.
It looks to me that some plugins failed to load or didn't load. It would have been interesting to look at the loeaded plugins (Help -> About) or see if the log contains informations about plugins. The stacktrace in comment 4 looks interesting. I filed bug 129307 for it. Setting this one to remind, we need more information to be able to track this down.
I agree that the info is really poor. Plug-in activation could be an interesting hint. I remember that I removed WTP, EMF, UML2 and GEF from the installation (hooked in via .link files) before I started this session.
As of now 'LATER' and 'REMIND' resolutions are no longer supported. Please reopen this bug if it is still valid for you.
