How to render core components in custom components?

Question

Hi,i got a piece of jsf code like this:
<h:panelGrid columns="1">
                //show1 part
                  <h:dataTable value="#{temp.nameFile}" var = "myL" rendered="#{temp.show1}">
                  <h:column>
                    <h:commandLink action="#{temp.createBean}" value="#{myL.name}" immediate="true">
                  <f:param name="name" value="#{myL.name}"/>
                  <f:param name="path" value="#{myL.path}"/>
                </h:commandLink> 
                 </h:column>
                 </h:dataTable>
          </h:panelGrid> and it may generates html code like this:
<table>
                    <tbody>
                         <tr>
                              <td><a href="#"
                                   onclick="document.forms['_id0']['_id0:_idcl'].value='_id0:_id2:0:_id4';
                                                         document.forms['_id0']['name'].value='ISO-3166';
                                                         document.forms['_id0']['path'].value='D:/Tomcat5.0/webapps/test/WEB-INF/iso3166.xml';
                                                         document.forms['_id0'].submit(); return false;">ISO-3166</a></td>
                         </tr>
                         <tr>
                              <td><a href="#"
                                   onclick="document.forms['_id0']['_id0:_idcl'].value='_id0:_id2:1:_id4';
                                                          document.forms['_id0']['name'].value='NAICS';
                                                          document.forms['_id0']['path'].value='D:/Tomcat5.0/webapps/test/WEB-INF/naics.xml';
                                                          document.forms['_id0'].submit(); return false;">NAICS</a></td>
                         </tr>
                         <tr>
                              <td><a href="#"
                                   onclick="document.forms['_id0']['_id0:_idcl'].value='_id0:_id2:2:_id4';
                                                         document.forms['_id0']['name'].value='UNSPSC';
                                                         document.forms['_id0']['path'].value='D:/Tomcat5.0/webapps/test/WEB-INF/unspsc.xml';
                                                         document.forms['_id0'].submit(); return false;">UNSPSC</a></td>
                         </tr>
                    </tbody>
               </table>now i want to write my own custom component and use a very simple tag to get the same output,and the tag may look like this:
<robin:category scheme="iso3166"> </robin:category>  It is very easy to render the tables out,and the f:param tags are rendered to hidden field,But you see,there is a command link component,and there is an "action" attribute whose value is bound to an action method.
I am not sure which part in the html code is rendered for the "action" attribute, and my question is how to directly render the html code for the command link's "action" attribute in the renderer of the component associated with the <robin:category> tag.
And it is very kind of you to give me some details about how jsf renders the method bindings to html and how to collect the information in the request to know which action method the clicked commandLink corresponds to if the "action" or "actionListener" attribute is specified!
maybe it is not good to include everything in a single tag, any suggestions are very welcome!
Best Regards:)

Hi Roosvelt,
Unfortunately, interactive components can only be created internally, and you cannot modify existing interactive components. We have heard this request before, and I hope to see this in a future release, but we have time frame for when this might be possible.
