So,
i've done this:
there's a init action that does:
public String execute() throws Exception {
Map session = ActionContext.getContext().getSession();
List cat = mgmt.getAllCategory();
session.put("category", cat);
return SUCCESS;
}
after that a jsp is display:
<%@ taglib uri="/struts-tags" prefix="s" %>
<s:form action="addItem" namespace="/admin" method="POST">
<s:actionerror/>
<s:textfield name="title" label="title" required="true"/>
<s:select label="category"
name="category"
list="category"
listKey="idCategory"
listValue="name"
multiple="false"
headerValue="-- Please Select --"
required="true"
/>
<s:textarea cols="15" rows="5" name="desc" label="desc" required="true"/>
<s:textfield name="prize" label="prize" required="true"/>
<s:textfield name="quantity" label="quantity" required="true"/>
<s:submit/>
</s:form>
but the problem is:
tag 'select', field 'list', name 'category': The requested list key
'category' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]
ideas?
