What is the technique that u have used to display data from one node to another ???
Have u used modules to reload the entire screen with the new node map details or are u just overwriting the existing screen with the new information??? In either case u will have to store the data temporarily in the application and redraw the polygons on reload. If the data is small (since u mentioned 3 polygons) u can store this information in the application itself to some persistent variable that u can access later even when the old node is reverted. If the data is medium then u should use shared objects as they allow to save upto 100 MB data on the client machine (provided the user has allowed it) But then again the user can disable shared objects or reduce the size limit for it thus causing u problems. If the data is large u have to go for a server side data storage approach. There is no other alternative. But i feel the first approach should suite u fine if u only need to store the data of the previous node & the current node. If u want to maintain all history then try the other 2 options. FYI ... I have used the first approach in my project on medium size data.
