Question

I’m developing adf calendar events form where the main page displays the calendar when user click on any date a small form appears to enter event details. I did most of the work but I’m facing a validation problem, I want when user save the form it checks if a field has a value and contains a number other than zero to save the form to the database if it has a zero it displays an error message, I hope you got the idea.

Note: I set ActionListener = #{bindings.Commit.execute} to the save button, I’m wondering if I can execute the validation when execute commit.

Regards,

create an IMPL file and override DoDML. You can then decide whether or not to update the database with the change. For a similar sample, see

From the entity impl you have access to its attribute for your 0, 1 comparison
