TaxonomicEditor Caveats¶

Unability to update disposed widgets¶

Exception:¶

org.eclipse.swt.SWTException: Widget is disposed

when updating widgets with a DataChangeBehaviour

Reason:¶

A widget that previously registered for data changes via ConversationHolder.registerForDataChanges() did not unregister itself properly while disposing.

Solution:¶

Make sure you have implemented dispose correctly.

Example:

public void dispose() {
   conversation.unregisterForDataStoreChanges(this);
   super.dispose();
}
