Hello All, I have a problem with the PostgreSQL module and empty query result: When a select query (named TestSearch bellow) return no tuple, the message is 'Error, exceptions.IndexError: tuple index out of range' In case of a Gadfly DB, the same query will return:'There was no data matching this select test query' My problem is that this query SQL method is use in a <!--#IN tag: <!--#in TestSearch size=50 start=query_start--> <!--#if sequence-start--> <!--#if previous-sequence-->etc... This cause a 'system unavailable' page to be rendered, instead of a ' no record something...' Do you know any workarround or DTML error trapping solution? Is it a bug inthe ZPyGreSQLDA module itself ? If yes it it inside the 'query' function? I actualy use an external method to filter the records, shall I also use a external method to do a 'try: except:' test on the TestSearch ? Thanks For any solution/help.
