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

> ------------------------------------------------

> Project: MyFaces Trinidad
> Issue Type: Bug

> Affects Versions: 1.2.8-core
> Environment: JBoss 4.2.1, Trinidad 1.2.8, JSF 1.2
> Reporter: Dushyant Agarwal
>
> 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?
