How do I perform Group Validations in h:datatable using custom Validators For instance lets say I have a data table containing one column containing values of States (NY,NJ...). In my custom Validator, I want to ensure that the state code does not repeat in any of the rows.
In the validator how do I get the ids for all the state codes to find the value in each of the component?
