This seems to affect Adobe Reader 9 for Mac OS X.
I have a PDF form made in LiveCycle. It has an HTTP Submit button. The data gets tranferred to the server without a problem (the data is getting saved by our php script), but when the script (on the server) returns the "Thank You" page, we get the following error:
"An error occurred during the submit process. Cannot process content of type text/html; charset=ISO-8859-1."
This works fine in Acrobat Reader (and Pro) on Windows and Acrobat Pro on the Mac; the only place we've encountered this problem is with Adobe Reader on the Mac.
I have tried changing the content-encoding coming out of the server to us-ascii and utf-8, but we get basically the same error, so I don't think it really has anything to do with the content-encoding, it's something with the Reader itself, or I'm just doing something completely wrong.
Can anyone point me to any documentation on why this isn't working?
Thanks!
