NPE in PortalDriverServlet when requesting a resource that doesn't exist
------------------------------------------------------------------------
Key: PLUTO-254
URL: http://issues.apache.org/jira/browse/PLUTO-254
Project: Pluto
Issue Type: Bug
Components: portal driver
Affects Versions: 1.1.0-beta1, Current CVS
Environment: Pluto 1.1 HEAD, Tomcat 5.5.17
Reporter: Elliot Metsger
Assigned To: Elliot Metsger
Priority: Minor
I have a portlet which attempts to load a resource that doesn't exist, and the
PortalDriverServlet throws an NPE. getPageConfig returns null:
else {
if (LOG.isDebugEnabled()) {
LOG.debug("Processing render request.");
}
PageConfig pageConfig = getPageConfig(portalURL); // getPageConfig
returns null
request.setAttribute(AttributeKeys.CURRENT_PAGE, pageConfig);
String uri = (pageConfig.getUri() != null) // NPE thrown
? pageConfig.getUri() : DEFAULT_PAGE_URI;
if (LOG.isDebugEnabled()) {
LOG.debug("Dispatching to: " + uri);
}
