Description Dirk Baeumer CLA 2001-10-10 22:45:40 EDT 
I implemented an IWorkbenchWindowActionDelegate and found some strange behaviour regarding selections:

	- if you shutdown eclipse and start is again then your contributed actions receive a selectionChanged call if the ouliner had the
	  focus. If for example the navigator or packages view had the focus on shutdown the actions don't receive any selectionChanged calls.
	- Selection changes in the text editor aren't forwarded to the IWorkbenchWindowActionDelegate.

One architectural issue: the IActionDelegate is the only concept where I receive selection changes for free (without registering for it).
Why isn't there some init method on IActionDelegate too. In this method I could access a selection service and hook up my own selection
changed listener if needed. Then we could remove the selectionChanged method.

Parts seem to be fixed. Unclear is

- if you shutdown eclipse and start is again then your contributed actions 
receive a selectionChanged call if the ouliner had the focus. If for example 
the navigator or packages view had the focus on shutdown the actions don't 
receive any selectionChanged calls.

Pls take a look. There is a similiar defect report about the selection change 
event being sent multiple times. When I find it I will link them in bugzilla.
Comment 4 Simon Arsenault CLA 2002-04-11 11:32:35 EDT 
Can you provide me with the name of the class that implements the 
IWorkbenchWindowActionDelegate which is having this problem? I can't seem to 
reproduce it with the readme example ones.
Comment 5 Nick Edgar CLA 2002-05-16 10:16:25 EDT 
Dirk, is this still a problem?  I see bug 4981 has been fixed.
If it's still a problem, please supply a test case.
Comment 6 Dirk Baeumer CLA 2002-05-16 11:57:13 EDT 
Can't reproduce
Comment 7 Simon Arsenault CLA 2002-05-16 12:04:04 EDT 
May have gotten fixed by someone else. Please re-open if you see the problem 
again.
