CommandStack deprecated method nottifyListeners(). [message #213278]

Hi,

I have the following code snippet:

public class DelegatingCommandStack extends CommandStack implements CommandStackListener
{
...
public void commandStackChanged(EventObject event) {
notifyListeners(); // DEPRECATED
}
}

The CommendStack#notifyListeners() method has been deprecated in Eclipse 3.1.
I couldn't find a replacement method to use. Has anyone had the solution for it?

Thanks
SL.

It may be deprecated, but with Eclipse API constraints it won't be removed
anytime soon.

A different pattern to get around it may be to use the delegating pattern
where your command stack contains an instance of CommandStack and redirects
all method calls to it.

Looking at the code below wouldn't that invoke an endless loop if
DelegatingCommandStack added a listener to itself?
