David,

>I finally figured it out after yanking out about half the hair on my head - I had registered the business object in a cGridList. I'm not sure why that wouldn't work, but when I removed the reference, the problem went away.

Although removing the reference caused the problem to go away, there's more that lurks under the surface here...registering the business object with a grid shouldn't adversely affect the business object.

Regards,
