We identified the problem was that the expression CAST ( [some integer property] as string) causes an SQL exception - it translates to native SQL CAST ( [fieldname] as text) causing cannot cast from integer to text (informix error code “IX000”,-9634 ). The informix database is 14.10.FC10IE I have attached a demo project with a unit test demonstrating the situation.
