Validation of database values throws validation errors
Validation triggers an error when a value coming from db violates the validation rule.
This happens during a clean GET request, when parameters from user are missing and the form is compiled with database values.

Only input data from the User must be validated. Database values can skip the validation step: if they are invalid, the problem will be reported on the next submit.
Solution: keep track of user-submitted parameters and perform validation only on these.
