Hi,
In my Action, I'm putting in the request the following object :
listcomp.add(new LabelValueBean("name","id"));
request.setAttribute("listcomp", listcomp);
like in the Struts-example.
In my JSP, I've got :
<jsp:useBean id="listcomp" class="java.util.ArrayList" scope="request" />
<html:form action="/project" >
<html:select property="company">
<html:options collection="listcomp" property="value"
labelProperty="label"/>
</html:select>
It's not working !!!
Help pls
Dams
