Hi, thanks for this pretty straight answer. But one more thing that bothers me. Why is this only an issue while testing? When my app is running, i am pretty sure that i dont use the DP_PLZ_DA class somewhere in the code before the worfklow with the query arrives. So why does it work in normal runtime mode?
