IHandler the chosen operation is not enabled

NOT USE popupMenus instead of Menus

isEnabled: should be set to true

isHandled:should be set to true

menu :

add it as a menu or menu item

Since they are impossible to find on the net here is the list of all base location uri's in eclipse that are used in the org.eclipse.ui.menus extension point:

menu:org.eclipse.ui.main.menu // the top-level menu

popup:org.eclipse.ui.popup.any // all pop-up menus

toolbar:org.eclipse.ui.main.toolbar // the top-level tool bar

toolbar:org.eclipse.ui.trim.command1 // the top left trim (main toolbar area)

toolbar:org.eclipse.ui.trim.command2 // the top right trim (perspective switcher area)

toolbar:org.eclipse.ui.trim.vertical1 // the left vertical trim

toolbar:org.eclipse.ui.trim.vertical2 // the right vertical trim

toolbar:org.eclipse.ui.trim.status // the status line trim

to access the menu/toolbar/popup of a part (view or editor):

menu:partid //the part's chevron menu

toolbar:partid //the part's toolbar (cannot contain other toolbars)

popup:partid //the part's popup menu (register the context menu in createPartControl first)

eclipse plugin menu gray out

check the handler class is correct set ,or not implement
