[jira] Resolved: (PLUTO-254) NPE in PortalDriverServlet when
requesting a resource that doesn't exist
[ http://issues.apache.org/jira/browse/PLUTO-254?page=all ]
Elliot Metsger resolved PLUTO-254.
----------------------------------
Fix Version/s: 1.1.0
Resolution: Fixed
In my portlet I had an improperly encoded url, which resulted in HTML like this:
<img height="1" width="1" src="media/org/jasig/portal/channels/CGenericXSLT/RSS/transparent.gif" alt=""/>
RenderConfig now returns the default page ID when the requested page cannot be found. If their is no default page found, PortalDriverServlet and RenderConfig log at the error level.
Committed r439719.
