Hi David,

Did you tried to check the value of the record in the BeforePost, or maybe
in the BeforeInsert event of your dataset? You can still set the value to a
valid one in those event, thus preventing the posting or the insertion of an
invalid value. You will probably have to check those events anyway, I was
using a dataset with an hidden field that was a autoinc key, and I did have
to set it to a proper value (I did not want at that time to alter the
definition of the field setting it to not required)...
