– Message Body ——————————-

Hi,

Another problem with 3.8 GA. When I go to the Preferences page Workbench->Editors->Annotations, I get an error dialog (“Unable to create the selected preference page”). The page is not created. An exception is logged in the Eclipse log.

Steps to reproduce:

1. Fresh install Eclipse 3.0.
2. Run and confirm the prefs page can be viewed.
3. Install MyEclipse Enterprise Workbench 3.8 GA.
4. Run and confirm that the prefs page fails as described.

The exception stacktrace follows:

!ENTRY org.eclipse.core.runtime 4 1 Aug 17, 2004 15:24:38.937
!MESSAGE Plug-in “org.eclipse.ui.editors” was unable to instantiate class “org.eclipse.ui.internal.editors.text.AnnotationsPreferencePage”.
