Using TNS SP1 introduces this problem - I recently spoke to a webM tech support person but haven’t heard back from him with a resolution as yet. He did tell me about another known issue though (and they have already released a fix for that), if you have SP1 installed on the client side as well - with SP1 installed, even if you set the TAP to proposed, the set inputs doesn’t work. They have a fix for that but I am yet to get it.
Once I get the fix and put it in place - I will post the results. Hopefully it would do away with the classCastException too.
