there is no consistency.

Hi,
I've noticed (on D7) that whenever you edit a string field (using something
like a TDBEdit linked to the CDS) setting it to "blank" the CDS set the
field value to emptyString ('') istead of NULL as other dataSets do.
Why is that? Is that any way to *fix* this behavior??
Thanks for any help,
Regards,
Anderson
 

1) It is *not* the case that "other datasets" necessarily set strings
you pointed me out. Many thanks Craig.
