### updateModel

    public void updateModel(javax.faces.context.FacesContext context)

  Perform the following algorithm to update the model data associated with this `UIInput`, if any, as appropriate.

  - If the `valid` property of this component is `false`, take no further action.
  - If the `localValueSet` property of this component is `false`, take no further action.
  - If no `ValueBinding` for `value` exists, take no further action.
  - Call `setValue()` method of the `ValueBinding` to update the value that the `ValueBinding` points at.
  - If the `setValue()` method returns successfully:
    - Clear the local value of this `UIInput`.
    - Set the `localValueSet` property of this `UIInput` to false.
  - If the `setValue()` method call fails:
    - Enqueue an error message by calling `addMessage()` on the specified `FacesContext` instance.
    - Set the `valid` property of this `UIInput` to `false`.

  Specified by:
    `updateModel` in class `UIOrderingBaseComponent`
  Parameters:
    `context` - `FacesContext` for the request we are processing
  Throws:
    `java.lang.NullPointerException` - if `context` is `null`

### validate

    public void validate(javax.faces.context.FacesContext context)

  Perform the following algorithm to validate the local value of this `UIInput`.

  - Retrieve the submitted value with `getSubmittedValue()`. If this returns null, exit without further processing. (This indicates that no value was submitted for this component.)
  - Convert the submitted value into a "local value" of the appropriate data type by calling `#getConvertedValue`.
  - Validate the property by calling `validateValue(javax.faces.context.FacesContext, java.lang.Object)`.
  - If the `valid` property of this component is still `true`, retrieve the previous value of the component (with `getValue()`), store the new local value using `setValue()`, and reset the submitted value to null. If the local value is different from the previous value of this component, fire a `ValueChangeEvent` to be broadcast to all interested listeners.

  Application components implementing `UIInput` that wish to perform validation with logic embedded in the component should perform their own correctness checks, and then call the `super.validate()` method to perform the standard processing described above.

  Specified by:
    `validate` in class `UIOrderingBaseComponent`
  Parameters:
    `context` - The `FacesContext` for the current request
  Throws:
    `java.lang.NullPointerException` - if `context` is null

### isEmpty

    protected boolean isEmpty(java.lang.Object value)

  Overrides:
    `isEmpty` in class `UIOrderingBaseComponent`

### isListEmpty

    protected boolean isListEmpty(java.lang.Object value)

### validateValue

    protected void validateValue(javax.faces.context.FacesContext context,
                                 java.lang.Object value)

  Description copied from class: `UIOrderingBaseComponent`

  Set the "valid" property according to the below algorithm.

  - If the `valid` property on this component is still `true`, and the `required` property is also true, ensure that the local value is not empty (where "empty" is defined as `null` or a zero-length String. If the local value is empty:
    - Enqueue an appropriate error message by calling the `addMessage()` method on the `FacesContext` instance for the current request.
    - Set the `valid` property on this component to `false`.
  - If the `valid` property on this component is still `true`, and the local value is not empty, call the `validate()` method of each `Validator` registered for this `UIInput`, followed by the method pointed at by the `validatorBinding` property (if any). If any of these validators or the method throws a `ValidatorException`, catch the exception, add its message (if any) to the `FacesContext`, and set the `valid` property of this component to false.
