Exception in QueryPageViewer
----------------------------

         Key: HBX-829
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-829
     Project: Hibernate Tools
        Type: Bug

  Components: eclipse  
    Versions: 3.2beta8    
    Reporter: Mike haller


If POJOs require thirdparty libraries which are not added to the classpath in the Hibernate Configuration, a lot of Exceptions occur. However, one of them is extremely annoying when it occurs as it is shown for *each* returned object in a HQL query result viewer. It is not possible to quit Eclipse in a clean way any more as the error message keeps popping up.

I suggest to catch problems occuring in the label provider and show them *once* in the problems view.
