Hi Kirk,
Rather than using command driven default on the initial load of the form you
could create a subclass to the action, for example "GetForm". In that class
you set the default values to true.
The parent class "SubmitForm" is changed to set the default values to false.
- Initial load of the form is made by calling "GetForm".
- When the user submits the form they call the parent action "SubmitForm".
The checkbox values actually submitted will be set and from what I
understand this will behave the way you want.
I work like this alot but in my case the "GetForm" does "real" work and
retrieves the existing "default" data from a database.
Hope this can be of some help.
Cheers,
Dick Zetterberg
