remember places

[Fabricio Pizzichillo]

hello to the group
I am developing an application, and I need at the time of requesting the login,remember that place comes the request, so you can continue browsing where you were
How do I remember the place where I come from?


greetings and thanks!

Your login place should have a 'redirectAfterLogin' String member, like this:

class LoginPlace extends Place {

 String redirectAfterLogin;

}

Optionally, you could go for, this is closely bound to GWT specific implementation:

class LoginPlace extends Place {

  Place redirectAfterLogin;

}

Will it still work if you refresh the browser (F5 key) or just jump up
the places by Back button? I think redirectAfterLogin may be null in
those cases as they are not set via previous activity class.

While a Place can hold any data structure, including other places, as you said once you refresh the browser, the data is lost. 

To circumvent this, Place must be considered to be a special kind of object in GWT, such that, the state of the place must be represented as part of url.  This is the reason for having a PlaceTokenizer. So in spite of having a reference to the toBeRedirectedPlace, you must also have a url param redirectTo=<xxx>, from which you can reconstruct the place on browser refresh. 

Hope this helps!
