We have an application that worked fine with a previous version of Rails (1.1.6). We recently upgraded to ver 1.2.2, and the controller handling the XML data stopped working. It seems to crop the data, and now we cannot receive data into the application anymore.
What is a recommended way to resolve this issue? Any tips and suggestions are greatly welcomed.
Did you get any error message in the log (assuming you are running in development mode)? You may try the breakpointer to isolate the problematic module.

Thanks much for asking! This is the message we see:

The weird part is that when it was working, we were accepting XML data with no problems. The CDATA was not getting cropped at all.. Whereas with 1.2.2+, CDATA gets cropped even before we have a chance to do anything to it in the controller code.
