Struts2 <s:select list=""> not working dynamically

I am using Struts2.

<s:iterator value="empReportFields" var="empReportField" 
    <s:select name="%{#empReportField.fieldName}" list="%{#empReportField.listName}" listKey="id" listValue="name" cssClass="search" headerValue="All" headerKey="All" />                                           

    <s:property value="#empReportField.listName" />
    // Here it is displaying proper list name                   
</s:iterator>

I am fetching out these data from my db. Now I am displaying specific list in select box (<s:select list="<ListName>" />) which is stored in column of my table (Database).

Normally it runs like.

<s:select name="emp" list="locationList" 
          listKey="id" listValue="name" 
          headerValue="All" headerKey="All" />

It will work well.

But I find simple select box with no list value in it. So what is the actual problem??

In short I want to call list dynamically.

According to how I understand the question you want to load <s:select list dynamically according to the iterator value.

If so just use the <s:select list like this <s:select list="#empReportField.listName".

Where <s:iterator value="empReportFields" is a list and inside that list another list or map named listName.

The s:select tag itslef has a list attribute where you can directly give the name of the list (in action class) you want to fill the dropdown with. You do not need an iterator for packing values into s:select dropdown.

Try this:

<s:select label="Select from here" 
        headerKey="-1" headerValue="Select"
        list="listNameHere" 
        name="feildNameHere" />

Here 'listNameHere' is the list in action layer and the 'feildNameHere' is a instance variable in action class which recieves the value selected by the user.
