Web Service Error - No Result Tree to Report On

Question

After successfully creating a web service reference and then using the 'Form and Report on Web Service' wizard I get an error, after defining the input items, at the 'Web Service results' Stage.
It states :
"No Result Tree to Report On
This Web service does not have a result tree in its definition that is appropriate for a report. You may wish to run the Form on Web Service wizard instead."
This web service returns an array of records and runs successfully outside of HTML_DB. Has anyone else had this problem ? I cannot find any information about this so far. I am using App Ex v2, 10g App Server and 9i (9.2.0.4.0) DB. The WSDL file for the web service is below.
Thanks

This has been the subject of bug 5394491 for several weeks now without any resolution. It looks like this error will prevent the use of Jdeveloper web services that use array parameters in the current versions of Application Express. We are not planning to use Application Express for this purpose any more as there is no information about the bug (or fix) forthcoming.
