However, the change that we made has nothing to do with an add in any way. We changed the enumerator which is only used in two places in the framework. 1.) When using a BO through a BBS or WBBS 2.) When using the GetEnumumerator() on the BO. Neither of these have anything to do with adding a new record. Additionally, we have actually pushed this release out into the field on our medical product and there are no issues, especially in this area. At this point, the only thing I can recommend is a sample that reproduces the error. You can change the sample that you sent previously with this change. But adding a new record and the change we made should not have anything to do with each other.

I have 2 tab pages, 1st tab page contains grid is to allow user to select/filter record. User can click a link in column to show record details. once clicked, it will switch to data entry page to show record details using AJAX UpdatePanel. After that, user click on new button to add new record, aspx is postback and error posted occurred. Also FYI, this was working all the time before using the fix memory leak business dll. Please advice. Thank you
