coldfusion, but i don't think it matters- i'm trying to take an actionscript object (the selectedItem of a datagrid) and cast it to another actionscript object (my VO). i suspected the mx_internal_uid property on the list item is messing me up, it's the only property that comes into the VO from the datagrid that the VO does not have- so i got to googling.
http://blog.smashedapples.com/2008/02/my-boring-base.html so now i have a base VO class that all my other VO's extend, and in this superclass I loop over properties and remove that one, and now- it all works fine. thanks, d.
