I got it. :)
All magic is behind freemaker.
dropdown.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Dropdown - Example</title>
<s:head theme="ajax"/>
</head>
<body>
<form id="selectForm">
<s:autocompleter theme="simple" name="upperValue" list="upper"
listValue="name" listKey="valueId" notifyTopics="/refresh" />
</form>
<s:url id="lower" action="lower" namespace="/dropdown"/>
<s:autocompleter theme="ajax" name="lowerValue" href="%{#lower}"
formId="selectForm" listenTopics="/refresh" />
</body>
</html>
struts.xml
<package name="dropdown" namespace="/dropdown" extends="struts-default">
<action name="upper" class="dropdown.DropdownAction"
method="upper">
<result>/dropdown.jsp</result>
</action>
<action name="lower" class="dropdown.DropdownAction"
method="lower">
<result type="freemarker">/options.ftl</result>
</action>
</package>
options.ftl
[
<#list lower as option>
["${option.name}", "${option.valueId}"],
</#list>
]
DropdownAction:
public class DropdownAction extends ActionSupport{
List<Value> upper = new ArrayList<Value>();
List<Value> lower = new ArrayList<Value>();
private String upperValue;
private String lowerValue;
public String doUpper(){
upper.add( new Value(1,"A") );
upper.add( new Value(2,"B") );
return SUCCESS;
}
public String doLower(){
lower = new ArrayList<Value>();
if( upperValue.equalsIgnoreCase("A") ){
lower.add( new Value(1,"a1") );
lower.add( new Value(2,"a2") );
}else{
lower.add( new Value(1,"b1") );
lower.add( new Value(2,"b2") );
}
return SUCCESS;
}
// geters and seters
}
Now I'd like to pass forward to my action list key value instead of list value.
Thanks,
Rodrigo Pereira
