[jira] Resolved: (ADFFACES-342) ChildPropertyTreeModel and
SortableModel will throw NPE if used outside of the JSF lifecycle
[ http://issues.apache.org/jira/browse/ADFFACES-342?page=all ]
Adam Winer resolved ADFFACES-342.
---------------------------------
Resolution: Fixed
Fixed (I think - no testcase, but we now look first for a FacesContext, and if that fails go to the ApplicationFactory)

> ChildPropertyTreeModel uses PropertyResolver to look at children. All good, but if you're outside of the JSF lifecycle, the following line is going to throw a null pointer exception:
> FacesContext context = FacesContext.getCurrentInstance();
> return
> context.getApplication().getPropertyResolver().getValue(parentData, prop);
> SortableModel has similar code.
> We've just had an internal user attempt to use ChildPropertyTreeModel from a filter. A little strange, but there's no obvious reason why these classes should only be useable with a FacesContext active (they don't take FacesContext anywhere in the API), and the Application can be retrieved from the ApplicationFactory (albeit more slowly).
