+/**
+ * TJuiEventParameter class
+ *
+ * TJuiEventParameter encapsulate the parameters for callback
+ * events of TJui* components.
+ * Any parameter representing a control is identified by its
+ * clientside ID.
+ * TJuiEventParameter contains a {@link getControl} helper method
+ * that retrieves an existing PRADO control on che current page from its
+ * clientside ID as returned by the callback.
+ * For example, if the parameter contains a "draggable" item (as returned in
+ * {@link TJuiDroppable}::OnDrop event), the relative PRADO control can be
+ * retrieved using:
+ * <code>
+ * $draggable = $param->getControl($param->getCallbackParameter()->draggable);
+ * </code>
+ *
+ * A shortcut __get() method is implemented, too:
+ * <code>
+ * $draggable = $param->DraggableControl;
+ * </code>
