Here is a link to a modified version of XIFF that should fix the bugs with Flex. Do a diff to see the changes. I was playing with this a week or so ago and hacked up the files a bit. The changes could be done much cleaner, I was in a hurry
The errors are long gone and I get a session in the Jive
messenger. With the new Jive installed tonight everything will be working. Thank you all for help and quick responses and a special thanks to Daniel Dura! Well done!
