Thanks Andrew. I'm going to try these ideas this weekend. Hope to get it done by the end of this week.

In the renderer for this new component, use the AjaxRendererUtils: public class HtmlArea extends UIComponentBase { // all the standard component stuff ... } public class HtmlAreaRenderer extends RendererBase { protected Class getComponentClass() { return HtmlArea.class; } protected void doEncodeEnd(ResponseWriter writer, FacesContext context, UIComponent component) throws IOException { writer.startElement("area", component); // write your non-onclick attributes here ... writer.writeAttribute("onclick", AjaxRendererUtils.buildOnClick(component, context), null); writer.endElement("area"); } } Then just put an a4j:region around the area if you only want a subset of values to be submitted & updated. The other alternative is to not use the buildOnClick, but instead just put an a4j:support under your custom component: <my:area ...> <a4j:support event="onclick" ... /> </my:area> Or if you don't want to create a custom component: <a4j:jsFunction name="onImageAreaClicked" ... /> <area ... onclick="onImageAreaClicked" /> This last one is the least effort obviously -Andrew On 5/25/07, Balaji Saranathan < <mailto:[EMAIL PROTECTED]> [EMAIL PROTECTED]> wrote: Thanks Andrew. I'm currently trying to use Ajax4Jsf on top of my MyFaces JSF application to enable Ajax capabilities. I'm trying to prototype a device UI where the "Onclick" JS events of a image Map opens up a different set of configuration parameters for the device. This keeps changing as per the Map Area clicked. I'm not sure how to achieve this. My code is something like this. <h:graphicImage id="mapImage" url="/images/ device_big.gif" usemap="#2004"/> <map name='Device1'> <area shape='rect' id='Key1' coords='178,71,203,83' title='Key1' nohref='True' onClick="alert('test');" /> <area shape='rect' id='Key2' coords='178,83,203,95' title='Key2' nohref='True' onClick="alert('test');" /> This onclick should be mapped to updating a couple of JSF components on the page.

If you want to submit one control, I would suggest the a4j:support from JBoss Ajax4Jsf that allows you to submit only one control and update the page using AJAX. There are many more answers to your question, so the question really is what is you specific use case?
