I know that with "isSelected ()" I can know if the checkbox is selected but, I am interested to know if the checkbox is not selected.
I tried doing:
chckbxProvincial == null;
!chckbxProvincial.isSelected()
It does not work for me.
I want to know if it is not selected to show a message.
I can not use an ELSE since I have many checkboxes and would like to validate this at all.
Any ideas?
