'Map' Transaction Property

Hi,

I have a transaction property of type 'map'. When I pass a static index value, it returns the string value fine. But when I pass a dynamic value, it throws an error - 'Expected token that differs from that found (Expected: '<EOF>', Found: '<IDENTIFIER>'). I am using a syntax of the format Transaction.MapProperty{Transaction.Index{/Rowsets/Rowset/Row}} . Any thoughts?

Regards,

V M.
