>So #1 is the game. With that said, what type of circumstances do you have in mind?

Simple method calls. For example, a textbox has a Validate method (not to be confused with Valid) which performs field validation. At run-time, the field validation rule comes over the wire (via XML) and must bind with the textbox Validate method. The textbox has no knowledge nor does it need to know what came over the wire.

I don't have time to provide all the details concerning our business rules engine. However, relying upon return values of simple method calls using BindEvents cannot be used in VFP9. As a workaround, the delegate method will use AEVENTS() to grab the source object and set a return property - this should work.
