We need to handle setting the default values based on the RPC routines.
The DefaultValueRoutine may be blank, so there may be no routine to call. I would expect the .getDefaultValue would return "" in that situation.
It would make sense to me to have the text boxes show "-" if it is disabled, or "ALL" if it is enabled.
On the middle tier, if there is a routine name to call, you can expect the field name to return is DEFAULT.VALUE.
