[gatein-issues] [JBoss JIRA] Commented: (GTNPORTAL-1664) NPE if portlet information cannot be retrieved

Chris Laprun commented on GTNPORTAL-1664:
-----------------------------------------
@Khoi, while that could be a potential solution to the issue, there are two problems with
this approach:
1. the ConsumerException doesn't mean that the portlet doesn't exist and such
it's not semantically correct to wrap it into a NoSuchPortletException
2. UIPortlet should handle any kind of exception that gets thrown better regardless of
what happens. The ConsumerException is caught in the generic catch block, however the only
action that is taken is to print the stack trace which leaves the UIPortlet in an
incorrect state.
The real solution is to properly handle any exceptions and put the UIPortlet in a state
that is correct at all times.

Basically, in the following code:
if (producedOfferedPortlet == null)
{
log.info("Could not find portlet with ID : " +
producerOfferedPortletContext.getId());
return null;
}
it's very likely that if producerOfferedPortlet is null, then the associated context
is as well... hence the NPE.
