### processDecodes

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

  Specialized decode behavior on top of that provided by the superclass. In addition to the standard `processDecodes` behavior inherited from `UIComponentBase`, calls `validate()` if the the `immediate` property is true; if the component is invalid afterwards or a `RuntimeException` is thrown, calls `FacesContext.renderResponse()`.

### processValidators

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

  In addition to the standard `processValidators` behavior inherited from `UIComponentBase`, calls `validate()` if the `immediate` property is false (which is the default); if the component is invalid afterwards, calls `FacesContext.renderResponse()`. If a `RuntimeException` is thrown during validation processing, calls `FacesContext.renderResponse()` and re-throw the exception.

  Overrides:
    `processValidators` in class `org.ajax4jsf.component.UIDataAdaptor`

### validateValue

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

  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.

### processUpdates

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

  In addition to the standard `processUpdates` behavior inherited from `UIComponentBase`, calls `updateModel()`. If the component is invalid afterwards, calls `FacesContext.renderResponse()`. If a `RuntimeException` is thrown during update processing, calls `FacesContext.renderResponse()` and re-throw the exception.

  Overrides:
    `processUpdates` in class `org.ajax4jsf.component.UIDataAdaptor`

### updateModel

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

### updateModel

    protected void updateModel(javax.faces.context.FacesContext context,
                               UIOrderingBaseComponent.UpdateModelCommand command)

### compareValues

                                    java.lang.Object value)

  Return `true` if the new value is different from the previous value.

  Parameters:
    `previous` - old value of this component (if any)
    `value` - new value of this component (if any)

### addConversionErrorMessage

    protected void addConversionErrorMessage(javax.faces.context.FacesContext context,
                                             javax.faces.convert.ConverterException ce,

    protected java.lang.Object createContainer(java.util.ArrayList data,
                                               java.lang.Object object)
