title: how can I add popup menu in right-click new->MyNewMenu on eclipse?
body: <p>I'm try to create a eclipse plugin... but how can I add a my new popup menu in the new context?</p>
  
  <p>for example I right-click on the project and put my menu inside of New->MyNewMenu</p>
  
  <p>to add a new item on menu File-New I'm using this</p>
  
  
  
  <pre class="lang-xml prettyprint-override"><code>&lt;extension
       point="org.eclipse.ui.menus"&gt;
    &lt;menuContribution
          locationURI="menu:new?after=additions"&gt;
       &lt;menu
             id="Test1.menus.sampleMenu"
  </code></pre>
  
  <p>but if I try popup:menu:new?after=additions on locationURI this not work...</p>
  
  <p>when I use the Spy plugin of RCP eclipse to know the popup id is returned</p>
  
  <pre class="lang-xml prettyprint-override"><code>menu:null?after=additions
  </code></pre>
  
  <p>how can I solve this problem?</p>
