Subject default values allowed in database action descriptor
Date Wed, 05 Sep 2001 16:25:44 GMT
Hi All,

Would anyone else find it useful to be able to specify default column values
in the XML descriptor file for the database actions?

Problem: Forms with checkboxes.

When Internet Exploiter submits a form with an unchecked checkbox it doesn't
do something sensible like ?param=no or ?param=off it simply omits the
parameter from the request parameter set.

This is causing me a problem when the database action tries to add the value
of the checkbox to a non-nullable database column as I get an SQLException.

If I could specify a default value for each field in the descriptor file
then when the parameters are processed and null is encounted, the default
value could be substituted.


I'll make this change and submit a diff.
