I have a problem that was not there before installing the latest updates as I remember.
I have a form with a List Lookup control that works fine until the selected lookup value gets deleted from the lookup list. The old behavior was displaying the text stored with the value (ID;#TEXT), SharePoint behavior is displaying nothing which is fine, but now the form is redirecting to the error page with "System.ArgumentException: Item does not exist. It may have been deleted by another user."
Any idea how to solve this issue?
