[news.eclipse.platform] problem disposing a view

[christoph.hilmes@xxxxxxxxxxx (kopinsky)]

Hi, 

i have a view that is registered as a selectionChange-Listener with an 
editor. In the method selectionChanged() of that view i do the following:

if (part!=null && selection!=null){
	if (part!=ViewTabelleninhalt.this && selection instanceof 
IStructuredSelection) {
		refresh();
	}
}else{
	ISelectionService s = 
getSite().getWorkbenchWindow().getSelectionService();
      s.removePostSelectionListener(this);
      s.removeSelectionListener(this);
	getViewSite().getPage().hideView(this);
	this.dispose();
}

That means, that when there is an editor present and there is an active 
selection i refresh the view. When there is no editor present, i want the 
view to be closed. But the way i close the editor doesnŽt seem to be 
sufficient. The next time i open the editor the selectionChange-event is 
triggered and although i had removed the view from the group of listeners, 
the above method still is executed.

How can i make the view really disappear? 

Thanks for any help.
Regards
Christoph
