Question

Struts 2 select tag filled by list property

Answer 1

+2 A:

<s:select label="Pets"
       name="petIds"
       list="petDao.pets"
       listKey="id"
       listValue="name"
       value="%{petDao.pets.{id}}"
/>

In the above. value = default selection, list = collection (of Map) coming from your action class, listKey = Key for map, listValue = value for map.

Edit (after looking at provided code):

your problem is that you do not have any getter in action class that corresponds with lstVehicles (which is mentioned in list property of your select tag)

Add this to your action class:

public List getLstVehicles ()
{
    return this.lstVehicles;
}

Answer 2

A:

dear all in JSP file i have

<s:select label="mainCategory" name="mainCategory"
            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]

do you have any suggestion
