[news.eclipse.platform] Can't check Nature of a closed project

[kozitza@xxxxxxxxxx]

If I call getDescription() on a closed project I get a ResourceException.  
I have a filter that only shows projects with a particular nature. 
However, if the project is closed I get the exception.  Maybe there is 
another way to check if a project contains a nature.  Here is a snippet of 
how I am doing it.

public boolean select(Viewer viewer, Object parentElement, Object element) 
{
     if (element instanceof Resource) {
          Resource resource = (Resource) element;
          try  {
           IProject project = resource.getProject();
           if (!project.getDescription().hasNature(MY_NATURE_ID));
                        return(false);
                   else {
                         // do the rest of the checks
                   }
         }
}
