Hi ,
I'm trying to develop
custom AJAX components, and i'm facing some problems on the
JSF technology architecture . Pay attention ;) :
An action on the page launches an XMLHttpRequest to a certain URL ( .jsf suffix). My aim is to have the JSF engine process only a certain part of the JSF tree , that is the part which contains the children of the component that launched the request ( for example a tabPanel component generates an ajax request , and only that certain tabPanel needs to be processed by the JSF engine ) .
My aproach on the problem was to build a listener which would :
The thing is that new UIViewRoot will get populated - by that i mean all the previous children erased - on renderResponse phase with the
JSP tags ( naturally because the engine would return the corresponding viewId ) . If I were to set an invalid viewId , e.g. a page that would not exist, than it would return a 404 page not found response.
What are your opinions on my approach , and what alternate suggestions do you have ?
