This is a repost from the Python forum:
Hi,
I have a python script being initiated within model builder. It takes input and output parameters from modelbuilder and runs a series of raster analysis functions. It creates the layers, reports back to modelbuilder, says it completed successfully, but then finishes with the typical "Failed to execute" message. I have confirmed thelayers are created and contain expected results, but the model doesn't reflect success - ie, no drop shadows on the tool and outputs. These outputs need to hook into a following function, but it won't initiate because of the perceived failure...
I could post the code and such, but really I think this is something simple or a known issue that somebody must know about! Any ideas?
Thanks in advance,
Matthew
