Hi Guys. Thanks for the replies.
@Paul: That was pretty much the conclusion I was coming to. The example I gave is a very much simplified example of the actual situation, as I didn't want to bore you all with the full scenario. The full senario is that I have a date property on a VO and I am parsing data and want to treat properties differently based on their type. Any property that has a default of "null" (pretty much only the simple values had automatic defaults) will have this issue @Ryan: I'd tried that function already and it has the same result as "describeType". As the default value for a "Date" data type is null, untill I actually assign a date variable to it, I will get "null". thanks!
