Catch Oracle Raise error

Hi,

Using the data server, any Oracle raise error (for personal error (-20000-20999)) can't be catch in progress.

Any other errors are correctly catch by the NO-ERROR paramater of the Run Stored-procedure whith a "if error_status:error ..." statement. When a Raise (or raise_application_error) append in orcale, it is imediatly display in progress with an ugly error message box.

I would like to catch these kind of error and display it correctly.

Thanks for any help.
