Aren't you using the 4.0 dtd?
It should be
<binding name="selectedList" value="userRoles"/>
>From Matt Raible <[EMAIL PROTECTED]>:
> In Tapestry 3, I had methods in my pages like the following:
>
> public List getUserRoles() {
> List selectedRoles = new ArrayList(getUser().getRoles().size());
>
> for (Iterator it = getUser().getRoles().iterator();
> (it != null) && it.hasNext();) {
> Role role = (Role) it.next();
> selectedRoles.add(role.getName());
> }
>
> return selectedRoles;
> }
>
> I then called them in my .page specification using:
>
> <component id="userRoles" type="contrib:MultiplePropertySelection">
> <binding name="model" expression="availableRoles"/>
> <binding name="selectedList" expression="userRoles"/>
> <binding name="renderer"
> expression="beans.multipleCheckboxRenderer"/>
> </component>
>
> Hower, it doesn't seem that this is possible with Tapestry 4 - even if
> I use expression="ognl:userRoles". I have to add an abstract
> getUserRoles() method and put the above logic in my pageBeginRender()
> method.
