title: E4 close a part from an innactive Perspective
body: <p>I have an e4 application that has two perspective: </p>
  
  <ol>
  <li><em>Operations</em></li>
  <li><em>Configuration</em> -> Contains (among other things) a part stack where the configurations are open. Each configuration in a part.</li>
  </ol>
  
  <p>When a new model is loaded all configuration parts are to be closed. This works fine if a load the new model when the configuration perspective is active. </p>
  
  <p>However, if I open some configurations in the <em>Configuration</em> perspective. Switch to the <em>Operations</em> perspective and load a new model.</p>
  
  <p>I can see in the logs that the code to close the parts is called and everything seems to be alright. However, when i switch back to the configuration perspective the parts are still visible an open.</p>
  
  <p>Could somebody tell me how to make sure that the parts are close, regardless of the which is the active perspective?</p>
