[Zope] - ZPyGreSQLDA errors when returning no rows

As the subject says, the ZPyGreSQLDA DA throws an error when the SQL query returns no rows. Is this to be expected? Do I need to write seperate DTML methods that handle that case? I was hoping to just get no objects returned, so my #in tags would execute their #else clauses. Ross -- Ross J.
