i created a ApplicationWindow class and added several actions. When I double click on a action, designer jumps to the run procedure so i can write code - as expected.
Since I dont like anonymous classes very much, I refactored the action to a nested class
But now when I click on that action Designer fails to jump to run() and show a message box that an error has occured.
In the Logfile I find the following exception:
- Code: Select all
!ENTRY org.eclipse.core.runtime 4 2 Sep 03, 2004 00:27:16.859
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.runtime".
!STACK 0

This happens both with the last august designer release and the new 01.09.2004 release on Eclipse 3 and 3.1M1
This also happens in any new project I create.
