When specifying GPServiceType.SUBMIT_JOB_WITH_MAP_SERVER_RESULT my resulting URL is null. when using GPServiceType.EXECUTE or GPServiceType.SUBMIT_JOB I get a valid URL.
Other Geoprocessing Models that I export to GPK return a valid URL when specifying GPServiceType.SUBMIT_JOB_WITH_MAP_SERVER_RESULT. I model my parameters and select add to display. The odd thing is when I run the tool in desktop, the result is not added to the display even through that is checked in the model. I have to add it through catalog and trying to add it through the result tab does not add it to the display either.
And I do have model parameter checked also.
First, make the model running on your desktop. Then, make a package out of the results. If you have still problems, attach you toolbox with model and associated data, then I would be able to help
