------------------------------------------------

                 Key: TRINIDAD-1230
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-1230
             Project: MyFaces Trinidad
          Issue Type: Bug
          Components: Components
    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?
