TrAXFilter breaks the XMLFilterImpl chain

           Summary: TrAXFilter breaks the XMLFilterImpl chain
           Product: XalanJ2
           Version: 2.5
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: org.apache.xalan.transformer
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


The method org.apache.xalan.transformer.TrAXFilter.setupParse sets its own
EntityResolver, DTDHandler and ErrorHandler in the case there is a parent. It
takes them from the transformer ContentHandler if it is suitable. This is wrong
because it breaks the XMLFilterImpl chain. It should only set "this", because
the TrAXFilter can be the parent of anther filter. It should therefore let those
events go through. If the TrAXFilter has a parent it makes no sense anyway to
something else, because there will be no more entities to resolve, DTD
declarations to handle or errors to be treated.

The effect of the error is that when a client sets, for example, an entity
resolver on the head of the filter chain, that resolver is never reached.
