Eclipse Activity Not Working

Question

I am trying to hide elements in the UI by means of activities like this

Answer 1

The pattern value for activityPatternBinding takes the format:

contributing plug-in id / local id

so you have to work out which plug-in contributes the menu item. Looking at the Eclipse Papyrus download the plug-in appears to be org.eclipse.papyrus.infra.discovery.ui.menu so the pattern is probably:

  pattern="org.eclipse.papyrus.infra.discovery.ui.menu/org.eclipse.papyrus.infra.discovery.ui.menu.toolbars.discoveryCommand">

(assuming isEqualityPattern="true", all the . characters need escaping for the regular expression version)
