I used h:outputLink as navigation link here.
The second page is a complete different view.
I tried to remove the dataTable on the second page and the error is gone.

@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)The explanation is discussed Here
Here is another useful links for Transaction Timeout
