/**
* TCallbackEventParameter class.
*
* The TCallbackEventParameter provides the parameter passed during the callback
* request in the {@link getCallbackParameter CallbackParameter} property. The
* callback response content (e.g. new HTML content) must be rendered
* using an THtmlWriter obtained from the {@link getNewWriter NewWriter}
* property, which returns a <b>NEW</b> instance of TCallbackResponseWriter.
*
* Each instance TCallbackResponseWriter is associated with a unique
* boundary delimited. By default each panel only renders its own content.
* To replace the content of ONE panel with that of rendered from multiple panels
* use the same writer instance for the panels to be rendered.
*
* The response data (i.e., passing results back to the client-side
* callback handler function) can be set using {@link setResponseData ResponseData} property.
