Is this me or is this a bug? [message #50818]

I'm using build number I20021108

I've got some code based around the logic example that the following code
snippet in an edit policy:

protected Command createDeleteCommand(DeleteRequest request)
{
Object parent = getHost().getParent().getModel();
DeleteCommand deleteCmd = new DeleteCommand();
deleteCmd.setParent((PolicyDiagram) parent);
deleteCmd.setChild((PolicySubpart) getHost().getModel());
return deleteCmd;
}

The problem is intermitent but what appears to be happening is the
following.

I'm changing the EditParts of a diagram, so new edit parts get added and the
old ones are removed, at which point the parent of the old part is set to
null.

This happens in removeChild in GEFs AbstractEditPart.

However, one of the old edit parts had the focus. And when I select a new
edit part a selectionChanged event is fired from AbstractEditPartViewer and
I am passed the old edit part now with a null parent.

Have I done something wrong?

AbstractEditPart.removeNotify() will deselect the EditPart and ensure that
it does not focus. When the old EditPart is deleted, it will get sent
removeNotify() by its parent before the parent is set to null.
