title: EMF - Limit Selections in Editor
body: <p>I've been googling my ass off with little success. I am using EMF to display a Model. I am trying to customize the Propertiesview for certain Elements. I want to filter the options, that it shows inside a dropdown box for a certain attribute. It seems like this is somehow connected to the addBehaviorPropertyDescriptor() function within the respective ItemProvider, but i am not sure what to do now :-/ </p>
  
  <p>I hope this rambling is even remotly comprehensable...</p>
