Nested properties do not work with html-el:image/html-el:submit ?

[Thomas Dudziak]

Hi,
I wanted to apply the ideas of the "Html Buttons and Struts - The Right 
Way" tutorial (http://j2ee-01.lagnada.com/struts/html-buttons.htm) to my 
struts app, but it does not work at all. Here's the JSP snippet :

<%@ taglib uri="http://java.sun.com/jstl/core"; prefix="c" %>
<%@ taglib uri="/WEB-INF/struts-html-el.tld" prefix="html-el" %>
...
<c:forEach var="curLink" items="${editForm.links}" varStatus="status">
   <html-el:text property="curLink[${status.count}]" 
styleId="normal"/><br/>
</c:forEach><br/>
<html-el:image property="buttons.addLink" alt="Add Link" src="add.gif"/>
<br/><br/>
<html-el:submit property="buttons.submit.name" 
styleId="button"/>&nbsp;&nbsp;
<html-el:cancel property="buttons.cancel.name" styleId="button"/>

</html:form>
The Form class has a corresponding getButtons() method which returns a 
bean that in turn has getSubmit(), getCancel() and getAddLink() methods. 
These then return beans with accessors for name, x, and y just as 
described in the tutorial.

When I click on any of these buttons, then I get this exception:
javax.servlet.ServletException: BeanUtils.populate
        org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254)

        org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254)
        org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482)

        javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
root cause:

        javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
which is caused by the fact that the BeanUtils try to access the 
property "buttons.addLink.y".

So is this a problem with html-el, or what is my error ?
regards,
Tom
