added protection from NPE

[Alexander198961]

Got Npe during database.insert(user); operation after added protection from npe seems working for me

[ccleve]

I'd rather figure out why we got the npe in the first place. Can you help me duplicate the error?

Looks like the line prop.dataType.isAssignable ... is causing the problem. Somehow the dataType isn't getting populated. Please post the code that is failing so we can see the issue.
