When selectionChanged method from IWorkbenchWindowActionDelegate is called? [message #452855]

Hello,

I have created a delegated action by using the extension wizard
(ActionSet) and now I would like to activate/desactivate the MenuItem
depending on the selection...
It seems that this can be done by "analizing" the selection in the
selectionChanged method but this method seems to be called only once and
not when the selection changed. Do I need to register my action to a
particular notifier?
Do you any idea on my problem?

Thanks,
Xavier

In your view within the Perspective the widget holding the selection
data do - tableviewer.setSelectionProvicer(this);
