How to set the IAction disable on popup menu [message #186359]

Hi all,

In my editor, I use GEF TreeViewer, I need to add a popup menu on the tree
viewer.
I use treeViewer.setContextMenu(menuProvider) method add a popup menu on
it.

In my popup menu there are some actions(IAction) add on it,
I want to set them disable when I selection some tree items.
But by use IAction.setEnabled(false) to set them disable, I got failed.

Where is wrong? Has any way to set the IAction disable on popup menu?

THX

If they are self implemented actions overwrite calculateEnabled().
