AGS call that works on 9.0.1.x does not in 10.x

Has anyone upgraded from 9.x to 10.x yet?

If so, have you found that any of your previous java scripts within Design Studio UI pages no longer work?

We have a java script embedded into our Design Studio modified version of PO20.1 which performs a couple of AGS calls. However, we have found that although this script has functioned seamlessly in 9.0.1 for years, it doesn't work in 10.0.4. When the script is in place, the PO20 form just hangs indefinitely upon execution of any action. When we remove the script however, the form functions properly again.

We believe that it has something to do with the URL and the fact that now on 10 we are going through the SharePoint layer for Workspace. We think it is likely a simple syntactical nuance that we are missing, but have not been able to make it work yet. However, when we questioned them, Infor has simply pushed it of by saying we would have to employ Professional Services for consultation on a fix.

Thanks in advance!
