> The JSF2 (RF4) supports ajax out of the box with its render-property.
> The render-property does only accept one or more server-side compontent ID's.
> Why does the render-value does not support classes?
> Or going further, why does the render-value does not support css-or jquery-like selectors?
> It would be very nice and clean to do something like this:
> <f:ajax render="$('.myclass)" .../>
> instead of this:
> <f:ajax render=":form, :text, :table, :menu" .../>
> myclass could be act as SERVICE:
> So I say myclass has the name "update_data_hobbies" and with that name I include all its components which should be considered by invoking the service "update_data_hobbies".
> <f:ajax render="$('.update_data_hobbies)" .../>
> <h:form class="update_data_hobbies"..>
> ..
> </h:form>
> <h:inputText class"update_data_hobbies"../>
> <rich:datatable class="update_data_hobbies".../>
> <!-- and so on.. -->
> (by the way, it would be cleaner to extract the service-name from the html5 data-attribute, for example data-ajax="update_data_hobbies").
> With the ability to enhance the property with css-jquery-like selectors, I can, for example, easily update all my table-elements:
> <f:ajax render="$('table')" .../>
> Go one step further, now the developer can maintain all the ajax-cluttered-code easily by searching for the name of the service, namely update_data_hobbies, within the code  to get or see all related ajax-components in one step without the need to search by ID. Go two steps further, jboss tools can then easily provide an Editor ("ajax-overview-editor") in which all correlated ajax-calls are viewed by its service.
> One of the main problems while developing ajax-sites is, that it is not very fast and easy to see and maintain all the components which are affected by ajax-calls. It will become harder, if the affected compontens are cluttered in more than one pages, which can happen when using templating future of jsf/facelets. It is annoying, to limit the render-value by its id, it is annoying, to search all the ID's which are listed in the render-value manually. It would leverage the semantic level of developing and maintain jsf-views by introducing the service "update_data_hobbies" instead of its correlated IDs. 
> JSF has the nice future of relating components in data and render via @ (for example @form which relates the form and its enclosed tags where ajax call is made). However, @ is very limited in selecting tags. But maybe, it would be reasonable to  extend the functionality and the meaning of the @-Operator as a @-selector.
> For this reason, I created a future request.
