1. open 2 properties view - 1 by default, other -> View Menu -> New Properties View
2. create zzz.xml with 
===
<html>
<head>
  <meta http-equiv="Refresh" content="0; URL=home.seam">
</head>
</html>
===
and open it in WPE;
3. see first Properties View -> "Properties are not available" - in it
4. in second Properties View - there are attributes
should be the same in both
5. click on first Properties View -> on "Properties are not available" area - get exception (1):
WARNING: Prevented recursive attempt to activate part org.eclipse.ui.views.PropertySheet while still in the middle of activating part org.eclipse.ui.views.PropertySheet

6. close WPE - get exception (2):
