I'm a bit confuse on how validation works as I am very new in XPages...
What I am trying to do is to validate the combination of 2 fields
1) Let say the 2 fields is "Make" and "Model"
2) I already create a view and name as "ViewCar"
3) I enter a data - Make is "Honda" and Model is "CRV" ( I combine and it become "HondaCRV")
4) I want to enter a new data and I want to make sure I will not enter the same data.
How can I do this? Can I just use validator to check this and prompt me.
