This problem happens to eclipse 3.6.2 and up.  

I want to add a menu item to the Show in menu when I right click my object in a view.  It should be activated only when one object is selected in my view. My extension is as follows:

  <extension point="org.eclipse.ui.popupMenus">
    <objectContribution
      id="my.popupMenu"
      objectClass="my.object.class">
      <action
        id="my.ui.popupMenu.id"
        enablesFor="1"
        label="%viewRuntimes"
        icon="icons/obj16/my.gif"
        menubarPath="org.eclipse.ui.navigate.showInQuickMenu/additions"
        class="my.MyAction"/>
    </objectContribution>
  </extension>

When I select 2 objects in my view I got the below error in the .log
!MESSAGE Plug-in 'my.ui' contributed an invalid Menu Extension (Path: 'org.eclipse.ui.navigate.showInQuickMenu' is invalid): my.ui.popupMenu.id

I know that the show in menu item is not available when multiple items are selected.  I guess the menu bar Path, org.eclipse.ui.navigate.showInQuickMenu/additions is invalid in this case.  However, should the code tests if meet the enableFor="1" because checking the menu bar path and throw me this error?
