No worries. Your stuff's a bit confusing. On your <html:form> you have an
action named "interest" and you don't specify a "name" attribute on your
<html:checkbox>. That means the checkbox tag is going to try and get the
form associated with your "interest" action (if it doesn't exist, it'll try
and create it) and then try to retrieve the property you named which is
"${interest.code}", plus the fact you are storing a "interests" object in
request scope.
I changed your code and the following worked for me, the only difference is
I don't use the "el" versions of the struts tags - just the standard ones:
<%
java.util.ArrayList interests = new java.util.ArrayList();
java.util.HashMap map = new java.util.HashMap();
map.put("code","ABC");
interests.add(map);
request.setAttribute("interests",interests);
%>
<c:forEach var="interest" items="${interests}">
<p>Interest: <html:text indexed="true" name="interest"
property="code"/></p>
</c:forEach>
... and it produced:
<p>Interest: <input type="text" name="interest[0].code"
value="ABC"></p>
