Method Details

• setErrorMessage

  default void setErrorMessage(String errorMessage)

  Sets a single error message to display for all constraint violations. The error message will only appear when the component is flagged as invalid, either as a result of constraint validation or by the developer through setInvalid(boolean) if manual validation mode is enabled.

  Specified by:

  setErrorMessage in interface HasValidation

  Parameters:

  errorMessage - the error message to set, or null to clear

• getErrorMessage

  default String getErrorMessage()

  Gets the error message displayed for all constraint violations if it has been set with setErrorMessage(String). Otherwise, gets the current i18n error message if the value is currently invalid.

  Specified by:

  getErrorMessage in interface HasValidation

  Returns:

  the error message

• setInvalid

  default void setInvalid(boolean invalid)

  Parameters:

  invalid - true for invalid, false for valid

• isInvalid

  default boolean isInvalid()

  Gets whether the component is currently in invalid state.
