defining DS field type as "string" crashes app in 4.1 if you call getType() on field

Hi, i am migrating my existing production app from 3.1 to 4.1 and noticed a kind of hard to find error.

datasource defined in XML, with a field:
if you define the field data type as "string" like you see above, and i have been doing since way back for some reason and then call
the app will crash, with the stack trace you can find in the bottom.

Kind of unexpected that an existing app would crash like this just by updating my smartgwt jars... Took me some time with debugging and system out'ing to find the source.
