    • setManualValidation

      public void setManualValidation(boolean enabled)
      Sets whether manual validation mode is enabled.

      When enabled, the validate(V) method skips validation, allowing the invalid state and error messages to be controlled manually.

      Parameters:
      enabled - true to enable manual validation, false to disable

    • validate

      public void validate(V value)
      Validates the given value using the component's validator and sets the invalid and errorMessage properties based on the result. If a custom error message is provided with HasValidation.setErrorMessage(String), it is used. Otherwise, the error message from the validator is used.

      The method skips validation if the manual validation mode is enabled, see setManualValidation(boolean).

      Parameters:
      value - the value to validate
