control ajax programmatically

[javatwo]

ajaxkeys can be used to reRender part of rich:dataList.

<h:form>

.......

     <a4j:commandButton action="#{carBean.updateCarPrice}" reRender="price" value="Submit"/>

     <rich:dataList var="car" value="#{carBean.listOfCars}" id="list"

          rows="6" type="disc" ajaxKeys="#{carBean.keyToUpdate}">

          <h:outputText id="price" value="#{car.price}" />

     </rich:dataList>

</h:form>

I am wondering if there is a way to tell ajax4Jsf to render the specific rows of rich:dataList on server side programmatically.

can i AjaxContext to add components? 

<a4j:commandButton action="#{carBean.updateCarPrice}"  value="Submit"/>

     <rich:dataList var="car" value="#{carBean.listOfCars}" id="list"

          rows="6" type="disc" ajaxKeys="#{carBean.keyToUpdate}">

          <h:outputText id="price" value="#{car.price}" />

     </rich:dataList>

keeping the ajaxKeys, removing reRender from the button action and adding "price" to ajaxContext did not work. I hope

to control ajax programmatically on server side, not in jsf page.

Thanks

I think this is possible, but you would end up in writing your own custom component where in encode phase, you write the markup for rerendering the particular rows programatically.

Thanks for reply. 

<rich:dataList> renderer should have supported this since ajaxKeys has been assigned a set of rows to be updated.

yes, I have looked at the example that uses jsf to control ajax. I like to control ajax programmatically on server side.

Dave,

How do you add 'price' to AjaxContext?
