Custom Control in menu item [message #1764133] |

Hi,
I would like to generate a menu item as a custom control (a checkbox-button with text in my case).
I implemented a org.eclipse.jface.action.ControlContribution then added to my MenuManger, but this way I am breaking an internal JFace assertion:
org.eclipse.core.runtime.AssertionFailedException: assertion failed: Can't add a control to a menu

Thank yoy Brian.
Having a checkbox item is enough here.
I blindly did not notice the IAction.AS_CHECK_BOX style bit for actions, which worked for me.
However, I would like the menu to stay open when clicking on this checkbox-ed item, to be able to toggle without having to re-open the menu each time.
How could I control that?
thanks,
-Piero
