history.back question

[janson12]

hi, im struggling with the following scenario:
i'm using some partial page reloads with <a4j:include> which causes the well known ajax history problem. does somebody have a solution to that? does richfaces provide a mechanism for that common issue? are there other frameworks that can be used in addition?
any idea very welcome!!

Working with browser history is our of scope for RichFaces framework.

I think that it is not supported out of the box.


As an answer to your original question:

A, maybe little outdated, discussion and generic framework is available here:
http://www.onjava.com/pub/a/onjava/2005/10/26/ajax-handling-bookmarks-and-back-button.html?page=1.

An interesting blog entry with regard to JSF and Ajax is available at http://www.jroller.com/wesleyhales/entry/g4jsf_and_gwt

elmar, thanks a lot. i already skimmed thru both articles. Do you have any experiences with one of the mentioned frameworks?
Meanwhile i think it's pure javascript problem:
the only thing i want to do is to reload the previously (a4j-) included subside when the users presses the browser back button. My "ajax-area" is controlled via backing bean so it shouldn't be too difficult to create some sort of subside history. The thing that still needs to be done somehow is to add some listener to the back button. I now know this is not a 100%-richfaces topic, but as i think a lot of people benefit from partial page reload supported by richfaces this issue could still be interesting enough in this case.
Cheers,
janson

I've read something about the tools but not tested or used them.

Based on the first article, as I see it, it is straight forward after set up of the JavaScripts:
- add an item to the history every time a corresponding AJAX request finishes (e.g. RichFaces oncomplete)
- add a listener (dhtmlHistory.addListener(historyChange);) and in the callback function you refresh JSF Ajax areas with information from the history event.

Ok, i tried the example shipped with the RSH and realized that it is not working properly with IE7. Changes on the page are not added to history, so back button stays disabled. Gonna try the dojo.back function...
