E.R,

>I'm trying to figure out if the issues with the AJAX update panel updating intermittently are related to the ObjectDataSource in general or if it's something about the MM.Net framework. I created a simple class decorated with DataObjectModel and with a method decorated with DataObjectModelType.Select that returned a MembershipUsersCollection.

My apologies for taking so long to get back to you...I'm in the midst of trying to reproduce your testing scenario but I simply can't get it to fail on my machine. At this point it would be best if you zipped up your sample app and sent it to us so I can check what's up!

Best Regards,
