JSF tag inside another JSF tag

Question

Hi,
Note: It's a bit of a long post but I will try to cut to the point without leaving behind any pertinent details.
I've created some simple custom JSF tags in the past. The tags usually consisted of one or two attributes that would be beans. The tags would then print out the data for those beans or process them and then output the results.
What I am trying to do now is a bit more complicated for me. I have a JSP page with a scriplet on it. It iterates over a bean containing a list of items. The loop adds those items to an HTML select menu one at a time. The outline of the code looks similar to this,
<% extract data List from the bean and store it in variable called dataList %>
<select>
<%
  for (int i=0; i<dataList.size(); i++;){
    ListItem item = dataList.get(i);
    String name = item.getName();
    String value = item.getValue();
%>
<option value="<%=value%>">
  <%=name%>
</option>
<%}%>
</select>
<h:commandButton id="gobtn" action="go_to_page" actionListener="#{action.fetch}" value="Go"/>What I want to do is take all the above code and put it into a custom JSF tag. This tag would contain all the scriplet code, output the HTML code and also the commandButton code at the end.
All of that is pretty easy except for the commandButton part. I am not sure how to output a commandButton from a custom JSF tag. How do I pass it the action.fetch part for the actionListener attribute? Can I create a commandButton object in my custom JSF tag and pass it this information?
I've followed a tutorial at this site in the past but it doesn't go into too much detail

Any help is appreciated,

Answer 1

I guess I missed some information. The dataList in the bean is stored in a HashMap. So some work has to be done with the bean before hand to determine what list to pull out and then "massage" it a bit for viewer consumption. This is not easily accomplished with the standard JSF html tags, hence my going with a custom tag approach.
Processing this bean and getting a list from the Hashmap in the bean before displaying it is easy, so is outputting the HTML. The hard part is rendering the commandButton with all the attributes I listed previously.
Is there a way in general to have other JSF tags nested inside a custom JSF tag?
