Re: GWT MVP architecture redirect link page with URL parameters passing
Hi Mahmoud,
Yes, this is very possible to do. Have any widget add a history
handler, and watch for any history change event, and then fire the
widget state accordingly as you see fit. I like doing it this way. You
can pass any number of parameters in to change the widgets/app state.
domain.tld#historyToken?[?params1=aparams2=b]
I do this in my core project I am building.
http://code.google.com/p/gwt-examples/source/browse/trunk/Core/src/org/gonevertical/core/client/global/QueryString.java
Here is how I manage the default History Observations:
http://code.google.com/p/gwt-examples/source/browse/trunk/DemoCoreEngine/src/com/gawkat/demo/client/DemoCoreEngine.java
private void initHistory() {
String historyToken = History.getToken();
if (historyToken.length() == 0) {
History.newItem(account_Things);
}
}
This will watch/observe the the querystring events (url):
History.addValueChangeHandler(this);
Hope that helps,

Hello,
I have followed the MVP structure while developing my project.
Once I hit the site URL, the History Manager loads the module by
inserting the default token to the history stack and then from there
the user can redirect himself to any part of the application by
changing the History token, which is basically the bit that comes
after the pound symbol (#) in the URL
My problem is: I'm unable to redirect a user to a specific token
without having to go through the default token and from there to
anywhere I want.
In other words, the URLs history usual follows this:http://domain#defaultToken
and from there I can go tohttp://domain#page1orhttp://domain#page2
without any problem.
But if i want to go directly tohttp://domain#page1i will be
redirected to the default token which ishttp://domain#defaultToken...
mainly due to this snippet of code:
this.container = container;
if (.equals(History.getToken())) {
History.newItem(defaultToken);
} else {
History.fireCurrentHistoryState();
}
So my question is: Is it possible to redirect a user to any part of
the application without having to start from the defaultToken page?
And can we pass in parameters using the URL only (i.e: how can the
user hit the following link without
errors?:http://domain#page3?param1=aparam2=b)
? How those it work?
To concertize the problem, I'm trying to implement an activation
link that if once the user clicks on it he will activate his account
given the userID and a encrypted code
(i.e:http://domain#activate?userID=12code=ht2oj34j2k5j6pk3
)
Any advice will do,
Cheers,
Mahmoud

Re: GWT MVP architecture redirect link page with URL parameters passing
Use something like History.newItem(page3?param1=aparam2=b);
This will rewrite the current URL and store it in the browsers
history. The onChange history event will then be fired.

Re: GWT MVP architecture redirect link page with URL parameters passing
That's parameter passing within the web application, what about the
first part of my question? the most important one to me
