getRowFromPath

Syntax

getRowFromPath(&startingRS, &path, &createIfNull)

Description

This method is useful for error processing. When your message expects a date or number field to be returned by the user, but the EMC cannot cast the value it gets back into one of those data types, it will put an error code in the exceptions stack. Along side that code in the stack, will be a row path. A row path is the path you need to follow to get to a specific row in a rowset. It follows the format (n)SCROLLNAME[(n)...] where n is a row number and SCROLLNAME is the name of the record comprising the rowset you want to retrieve in that row. When you get an error of one of these 2 types, you can call this method, passing in your message rowset, the rowpath in the error stack, and false. You will be returned the exact row where the error occurred (the name of the record and field are also in the error stack.
