Problem with validation

Hi, I’m using a custom validation method to validate some logic.
But i realized that the database query is running two times.
So the database is being called twice.

The validation methos just display an error if array items are


Prova Load (0.4ms)
[“a”, “a”]

Questao Load (0.4ms)
[“a”, “ab”]

What’s wrong with my code ?
