Hello:I've got a script that works consistently in Catalog/Desktop but it fails unexpectedly once published as Geoprocessing Service. It's driving me nuts and I hope I'm missing something obvious.Also: What are good ways to troubleshoot it? Is there a way I can force Server to keep the resulting data so I can look at it? Can I get Flex to output messages at my will from the script? Ie. the way I can arcpy.addMessage("var X broke!")The code below breaks at the last line I have provided with the error: "C:\arcgisserver\directories\arcgissystem\arcgisinput\rq10.GPServer\extracted\v101\published_data\rq.py", line 120, in <module>
boxWidth = boxXMax-boxXMin
NameError: name 'boxXMax' is not defined
Failed to execute (rq).
I assume the error is because boxXMax is never being made, which I assume because row3 is null because there are no entries for the SearchCursor. But why is that data coming back empty? How could I test or investigate this?
