Maintaining state between multiple entries to same GWT module


A while ago i asked this question GWT Multiple html pages and navigation
Although i was first satisfied with the simplest solution i used, which is similar to the one suggested here also Problem with multiple entry Points in the same module. But a major drawback which i am running into is that, The data which i get and build from the first run of the onModuleLoad() is not available in the susequent run of the onModuleLoad() for the same EntryPoint class. For eg. lets say i create a instance of a class LoginSessionInformation on the first run,now how do i access this instance when the onModuleLoad is called the second time.

Thanks

Edit: This is purely for client side, as i am taking the login information in the first run and constructing class LoginSessionInformation, and planning to pass that to server the second time.

You have not said where all your state is.. if its on the server, your in the same session so its all there. If its a client side problem, then one place to store stuff is in a cookie or to probe the server again if ncessary. Many times its okay to leave stuffon the server and do your work there on the data rather than passing back lots of data to the client and doing some processing there..

You can pass the state in the URL token and use the history handler.
