I bet there is a small error in the CTH. Please post the code for use to see and I bet we can get it worked out.

There have been similar reports in the past. Would you try the latest version (2.3) to see if you still have the error? Also, this known bug may be related: http://issues.apache.org/jira/browse/IBATIS-357 It might seem unrelated on the surface, but I belive the error maybe in the same area of the code. Anyway, let us know if it's still broken with the latest version. If we can get a reproducible test case, then we can take a look at it.
