dear all

       list="mainCategory" listKey="id" listValue="name"
value="%{mainCategory.{id}}" required="true" />
in struts.xml file i have
<action name="add" class="com.baibai.action.C0032_AddAction">
<result name="success">/C0031_List.jsp</result>
<result name="input">/C0032_Add.jsp</result>
</action>
in Java file i have
public List<DropDownList> getMainCategory() {
List<DropDownList> ls = null;
DropDownList dr = null;
 dr.setId(0);
dr.setName("--please select one of these--");
ls.add(dr);
 return ls;
}
but the error appear
tag 'select', field 'list', name 'mainCategory': The requested list key
'mainCategory' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]
