Tell us the version. Redeploy of rar classes is not supported in 2.4.4, this is so your app can get the the rar classes. In 3.0, I think all versions, the classes should update. Wait for the next binary release, it should be way better than the predecessors.
Yupp, using version 2.4.4 :(. I knew that it had to be something obvious. *doh*
Next binary release... of 3.x or will 2.5 support .rar re-dployment?
2.x series will not support binary redeployment of rars. The 3 rc1 is now out, and it does.
