      • getFamily

        public String getFamily()
        Description copied from class: UIComponent

        Return the identifier of the component family to which this component belongs. This identifier, in conjunction with the value of the rendererType property, may be used to select the appropriate Renderer for this component instance. Note this method should NOT return null

        Overrides:
        getFamily in class UIInput
        Returns:
        the component family (not null).
      • getGroup

        public String getGroup()

        Returns the name of the radio button group.

        Radio button components having the same group within a UIForm parent will uncheck all others when being checked. If the value attribute is absent then the one from first component of the group will be used. If the UISelectItem child is absent then the one from first component of the group will be used.

        Returns:
        The name of the radio button group.
        Since:
        2.3
      • setGroup

        public void setGroup​(String group)

        Sets the name of the radio button group.

        Parameters:
        group - The name of the radio button group.
        Since:
        2.3
      • validateValue

        protected void validateValue​(FacesContext context,
                                     Object value)

        In addition to the standard validation behavior inherited from UIInput, ensure that any specified value is equal to one of the available options. Before comparing each option, coerce the option value type to the type of this component's value following the Expression Language coercion rules. If the specified value is not equal to any of the options, enqueue an error message and set the valid property to false.

        If UIInput.isRequired() returns true, and the current value is equal to the value of an inner UISelectItem whose UISelectItem.isNoSelectionOption() method returns true, enqueue an error message and set the valid property to false.

        Overrides:
        validateValue in class UIInput
        Parameters:
        context - The FacesContext for the current request
        value - The converted value to test for membership.
        Throws:
        NullPointerException - if context is null
