Description Adrian Grealish CLA 2006-04-28 15:24:53 EDT 
When you turn project specific settings off on the Annotation processing Dialog then hit apply then re-enable project spcific settings the dialog is in odd state where the rest of the dialog is still disabled for user edit.

Repro
---------
1. Create Java project
2. Go to project properties --> Java Compiler --> Annotation Processing
3. Enable project spcific settings
4. Enable annotation processing
5. Hit OK
6. Go back to project properties --> Java Compiler --> Annotation Processing
7. Disable project specific settings
8. Click apply
9  Re-enable project specific settings, now unable to to use any other component on dialog because they are not active

Essentially the same as bug 137398, or bug 111144.  This is yet another instance of the problem where WorkingCopyManager has cached a copy of a node, and that node then gets deleted (because disabling project preferences removes the per-project settings node).

The reason the controls are disabled is that the initialization code has failed.  In the error log, note the following (partial) stack:

java.lang.IllegalStateException: Preference node "org.eclipse.jdt.apt.core" has been removed.
