[ http://issues.apache.org/jira/browse/PLUTO-281?page=all ]
Elliot Metsger resolved PLUTO-281.
----------------------------------
Resolution: Fixed
PortletRegistryListener added to the portal's PortletRegistryServiceImpl in
r487453. Marking as resolved for now and we can probably close the issue if
noone finds a problem with this solution.
> NPE thrown when trying to add a hot deployed portlet to a Pluto page

> Key: PLUTO-281
> URL: http://issues.apache.org/jira/browse/PLUTO-281
> Project: Pluto
> Issue Type: Bug
> Components: portal driver, portlets-admin
> Affects Versions: Current CVS
> Reporter: Craig Doremus
> Assigned To: Elliot Metsger
> Fix For: 1.1.0
>
>
> Adding a hot deployed portlet to a page using the Page Administrator Portlet
> results in a NullPointerException which points to line 161
> PortletModeAnchorTag.java (see stack trace below). The hot deployment was
> done using the Tomcat manager application.
> The proximal cause of this problem is a null PortletWindowConfig object.
> However, if a portlet-app record for this portlet is added to
> pluto-portal-driver-config.xml, and Pluto is restarted, the portlet can be
> sucessfully added to a portal page using the Page Administrator.
> Althought null checks can fix the problem in the PortletModeAnchorTag class,
> the root problem is that we need to notify users of this problem and its
> solution. I have found this NPE also occurs if there are errors in manually
> updating the config file or if I forgot to update that file after manually
> deploying a new portlet.
> TOMCAT ERROR PAGE OUTPUT:
> description The server encountered an internal error () that prevented it
> from fulfilling this request.
