Woot!  Glad you're fixed.  Let us know when you need help on your next gremlin.

Hi JSantos, Ben,

Wow it must have been a long night for you JSantos thinking about this issue

I knew the combination of using filters in such a way had something to do with this issue after all and I am glad you got that figured out.

Now, it looks like you inherited this project and after this experience, I would be very careful with the miss-used of BO.Filter or child auto filtering in other part of the code.  As you have seen, the final exception being thrown by .Net not necessarily point you in the right track as to what is causing the error.

I learned over the years that StrataFrame design and logic used for the Business Object is rock solid since my applications never fail due to an internal SF error or memory leaks, it is always due to an improper used of a feature in the BO and 99% of the time a BO.Filter or BO.Sort is involve.

Enjoy!!!
