Hello,
i have a problem with button click; in my form when the user clicks a button i must execute the True action only if an item has value; otherwise i would like to show an alert message like "You should specify <item> value ...".
It seems a simple problem, i've tried to insert the 'Item is not null' condition and the alert as the false action but it does not work.
Which is the Apex-way to solve it?
Thanks in advance.
