title: Contribute an "editorAction" via org.eclipse.ui.menus extension point
body: <p>In many documents like <a href="http://www.ibm.com/developerworks/opensource/library/os-eclipse-3.3menu/index.html" rel="nofollow">here</a> it is described, that old extension points <code>org.eclipse.ui.actionSets</code>, <code>org.eclipse.ui.viewActions</code>, <code>org.eclipse.ui.editorActions</code>, and <code>org.eclipse.ui.popupMenus</code> from Eclipse 3.2 were replaced by the new <code>org.eclipse.ui.menus</code> extension point in Eclipse 3.3. </p>
  
  <p>So my simple question: 
  How do I use the new extension point <code>org.eclipse.ui.menus</code> to contribute to an editorAction toolbar (<code>org.eclipse.ui.editorActions</code>) ?</p>
  
  <p>I tried stuff like the following in many different <code>locationURI</code> values but it never worked.</p>
  
  <pre><code>   &lt;extension point="org.eclipse.ui.menus"&gt;
        &lt;menuContribution locationURI="toolbar:my.editor.id"&gt;
           &lt;command
                 commandId="my.command.id"
                 icon="icons/somicon.gif"
                 label="Do my command"
                 style="push"&gt;
           &lt;/command&gt;
        &lt;/menuContribution&gt;
     &lt;/extension&gt;
  </code></pre>
  
  <p>My command never shows up and I dont get any feedback in the console. So what is the correct property for <code>locationURI</code>, to get my command in there??</p>
  
  <p>The command works on other toolbars, it also works via the old extension point (with modifications of the command class). </p>
  
  <p>Why I need the new extension piont? 
  Because it not only supports commands, but also controls, where you can contribute more than a simple button. </p>
  
  <p><strong>Final update</strong></p>
  
  <p>The solution below intended to replace the functionality from editorActions extension point. Due to the bug mentioned in the answers last comment, that replacement is not really useful. 
  Anyhow accepted...</p>
