Method Summary

void	actionPerformed(FormEvent event)
protected ViewContext	createNormalScreenContext(ViewContext vc, Envelope newbBox) This Method adapt the normal size screen context with the new changes applied in the full screen view, ex.
protected ViewContext	getViewContextFromSession() Extracts the Xml of NORMALSCREEN_MAPCONTEXT from the session and transforms it to a ViewContext
protected void	initialize() Initializes the global variables of the class
protected void	setCurrentContext(ViewContext vc) Takes in viewContext converts it to a html of the viewcontext and display it
protected ViewContext	setToNormalScreen(RPCWebEvent rpc)
protected void	validate(RPCWebEvent rpc) ValidateRPC looks in the RPCStruct for all needed elements and gotoErrorPage in case an element is found or wronglz formated, this is useful so that we won't need to check later for anz variables, simply get them and start Working
protected void	validateBBox(RPCMember bboxRPCMember) Validates the data in the struct to make sure it contains a valid bbox
protected void	validateLayerList(RPCMember layerListRPCMember) Validates the data in the struct to make sure it contains a valid layerList
