forEach Loop inside form

[jcosano]

I have this loop inside a form:

    
<select name="assignedUser">
   <c:forEach items="${subunitUsers}" var="aUser">
       <option value="${aUser}">${aUser}</option>
    </c:forEach>
 </select>
 <input type="hidden" name="assignedUser_type" value="String" />‍‍‍‍‍‍‍

And I have an error that property aUser doesn't exists. (It's true I only have subunitUsers that is an arrayList of Strings)

I simplify this code using this:

<c:forEach var="i" begin="1" end="10" step="1">
     <c:out value="${i}" />
    <br />
</c:forEach>
‍‍‍‍‍‍

And Exception is the same:

Then… I'm doing something wrong? or is it a bug?

My target:
I have an arrayList variable with String and i would put this values inside a select values of the form.

[jbarrez]

It's not jsp tags that are used inside the forms, but freemaker.
You can do loops in various ways, for example: http://fmpp.sourceforge.net/freemarker/ref_directive_list.html

[jcosano]

Ok, I will try it!

[jcosano]

<#assign x=3>
<#list 1..x as i>
  ${i}
</#list>

[jbarrez]

I verified it, and you are correct. The internal form rendering engine has been switched from Freemarker to Juel (hence my link to the Freemarker website).

However, I cannot find staright away how to do loops with JUEL.
Could you file a JIRA describing that it would be better to switch back to Freemarker again ?

[jcosano]

I create:
http://jira.codehaus.org/browse/ACT-229

[cr2121]

I hava the same question.
