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)...

Hi jpi,

I've decided to set the (default)value in the OnNewRecord event, preventing
that language specific constants could affect our programs behavior. If the
problem will appear anyway, I'll try it as you've recommended.
