[Zope] Problem with saving error_message to db

Hi, I want to save the error_message and/or the error_type/error_value to a connected Interbase DB. When an error is raised I call an sqlmethod from the standard_error_messege that should save the error_messeg to Interbase. The problem is that the transaction of the sql method probably rolles back because it is called from standard_error_message. Is there a way to submit the error_message. (commit the transaction) Thanks in advance Jens
