Hello everybody,
I want to use a ColumnViewerEditorActivationListener to catch the event beforeEditorActivated for a TableViewer-Cell. This listener is connected to the ColumnViewerEditor in the constructor of my EditingSupport-class. But "beforeEditorActivated" is never called, because the ListenerList editorActivationListener in ColumnViewerEditor is null!
If I attach the ColumnViewerEditorActivationListener in my EditingSupport.initializeCellEditorValue-method, I can atleast catch the events afterEditorActivated and afterEditorDeactivated, but thats too late, I need to catch the event beforeEditorActivated too.
What could be the cause of it? Am I doing something wrong? Where is the right place to attach the ColumnViewerEditorActivationListener to the ColumnViewerEditor?
Regards,
Arne jans

ColumnViewerEditor comes from jface, so I've copied the question to the
jface newsgroup.
