Hi The problem basically is there is no way to detect which javax.faces.ViewState hidden fields belongs to a specific "window" or view from the client side (javascript). To solve this it is necessary to pass a "marker", and use it to find all related javax.faces.ViewState hidden fields and update then when an ajax operation occur.
The javascript fix (no_portlet_env), only works on servlet case, because it assumes all forms belongs to the same view and the client side code just update all of them. So, in portlet case, since a page is a composition of multiple views, in theory the "environment" should generate an unique identifier. In practice, each portlet is a "window", and each window requires its own windowId. To solve this, the portlet container should provide a way to identify a page from other in the same browser, and then use that identifier to build another one "per portlet". At the end, to solve this problem it is necessary to add windowId concept on the spec. In theory it is possible to create a fix and add the missing windowId hidden field using a custom ResponseStateManager wrapper and adding some code on the client side (changing some parts of jsf.js), but instead it is even better to fix the spec. regards, Leonardo Uribe
