I've changed the ApplyDiffgram command to use an alias instead of the CA, and also specified keyfield for the XMLAdapter. The ApplyDiffgram is now working, but I'd still like to know what the error applied to. (But I'm leaving in the morning for vacation, so I can't answer any replies for a while.)

>I have a diffgram that's going against a cursoradapter with 38 fields. When I try to ApplyDiffgram, it's giving me a "Function argument value, type or count is invalid". Below is the code I'm using. Is this error from the CA object I'm passing to ApplyDiffgram, or is it a problem with the diffgram itself?
