Yes.  That's because the wtnRecGet() procedure only validates against 
DDS specifications (or equivalent SQL).  And as far as I know, there's 
no way to specify a date range in file field descriptions.

But that's inline with the three validation stages that we discussed 
earlier in this thread.

1. before a form is submitted to the server (browser level validation).
2. before a field is mapped to a data structure.
3. before a record is written to the database.

The wtnRecGet() procedure automatically takes care of stage 2 validation 
& mapping.  You could add RPG logic for stage 3 date range validation.
