Document Literal WSDL Processing - maxOccurs="unbounded"

           Summary: Document Literal WSDL Processing - maxOccurs="unbounded"
           Product: Axis
           Version: current (nightly)
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: WSDL processing
        AssignedTo: axis-dev@ws.apache.org
        ReportedBy: mike_herrick@mentor.com


Axis creates methods like: 

    public void setNameofComplexType(int i, samples.pubsub.Message value) {
        this.message[i] = value;
    }

for elements that reference complexTypes and set maxOccurs"unbounded".

If this method is used, at runtime, a NullPointer is generated because 
internally, the array (this.message[]) is not dimensioned.

I am attaching a WSDL, an example of one of the classes in question and a basic 
impl of the web service that attempts to use this method.
