I cannot really help you but i got the same issue once i've tried to integrate jcifs in my application.
Do you use a filter for the authentication? I think it has something to do with this one.
Once i've added the filter to the chain i had problems in IE that none of the commands where going down to the server.. After several days of trying i gave up for the moment.
However, we have jcifs running in another seam application but i had no time (budget) to investigate more..
Thanks for the response Martin. I will do some tinkering with the filter and see if I can't figure out what the issue is there. It's a help to know this is probably jcifs specific and not some other random problem.
Well, I removed the filter and I'm still experiencing the same issues, so it seems like it's got to be some kind of dependency/classloader conflict. Anyone else have any ideas?
I removed the jcifs dependency and confirmed my app was back to a working state. Then I re-added it and sure enough, just adding the dependency is causing the commandButtons to fail. I really hate incompatible dependency issues like this because they are never documented anywhere and I get no error message at all, so this has been a joy to diagnose.
Any ideas for a workaround?
