Question

The situation is as follows:
A user on the client side enters some data and presses a command button that initiates an ajax request. Depending on the input data the JSF Bean on the server side redirects to different pages. But in addition the HTML5 features localstorage respectively sessionstorage should be updated on client side, also depending on the results from the bean. For the storage some data entered from the user is necessary, so that the java script for the storage has to be within the original page.

Now, the problem seems to be that after the response the redirect is always done first, before executing the js function and so it is not possible to access the input data from the user on the client side of curse.

I tried things for calling the js function after pressing the command button like “oncomplete” on the client side using callback parameters (redirect takes place earlier) or RequestContext.execute from the server side (but this internally also uses the oncomplete event i think).
One possible solution I could imagine is to use window.onunload on client side and a hidden input formular to get the result of the bean. But isn’t there a better solution?

Answer 1

You need to redirect by JS instead of by JSF. Return null from action method so that it returns to the same page and then execute the following script to perform a redirect in JS.

window.location = newURL;
