Think of a shopping cart checkout.
I have a text field "qty" and a button "add" on list page for each row.
I want to add+1 to "qty" when the user clicks "add" and display the new value. I also want to save this new value to the database. I can do this easily by refreshing the page each click, but this looks clunky.
Any ideas? The pageid and ctrl.setValue() don't seem to be available from inside the button "Client Before".
Thanks for your help.
