extends org.springframework.web.servlet.tags.RequestContextAwareTag

Used to swap the command object in the request with that supplied by the getCommandObject method of the supplied controller. Written specifically to swap the command object when combining many pages from a MultiPanelFormController into one (Ie, print all panels) when the command object is of different type for one or more of the controllers for each panel. Use inline within the page to swap the command object as the page renders.
