Matthias We├čendorf commented on TRINIDAD-1230:
----------------------------------------------

This is similar to TRINIDAD-1221, which was filed before this ticket, so I mark this as duplicated.

> Hi,
> I have a JSF page containing a tr:panelRadio component. Inside this component I have
put tr:showDetailItem
> which contain the corresponding component to render. 
> There are more than one tr:showDetailItem components inside the tr:panelRadio component.
And
> all the components are exposed to a backing bean(There are instances for every component
on
> the page, in a managed bean).
> On deploying my war file once there appears to be no problem.
> But on redeploying the war in the server an exception occurs stating
> [application] JSF 1004: Could not instantiate class org.apache.myfaces.trinidad.CoreShowDetailItem.
> Then it gives the stack trace of a faces exception with message java.lang.NullPointerException
> I am using the JBoss 4.2.1-GA application server.
> I have used trinidad-impl-1.2.8.jar file in the WEB-INF/lib folder.
> What should I do to remove this problem?
