+/**
+ * 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.
