Yes .. Have a look at the docs for LookupDispatchAction .. 
That would solve your purpose ..

Is there someway we can do the same thing, without making a server call on
every change event of the first select control ? 
Again, we want to make minimal use of JavaScript. 

Thanks in advance

Anindito

Something like Below ..

The "Onchange" event will trigger the Submission to another action which
then keeps the collection in request/session scope and select Box B is then
populated ..See the code below ..




<script>
		function callAction(){
			document.forms[0].action =
"<%=request.getContextPath()%>/populateAction.do";
			document.forms[0].submit();
		}
<script>

		<html:select property="A" onchange="callAction();">
			<html:options collection="collection1"
name="Form"
property="value" labelProperty="label" />
	    </html:select>

		<html:select property="B" >
			<html:options collection="collection.areas"
name="Form"  property="value" labelProperty="label" />
	    </html:select>

Well at the least you would probably want to use some javascript to trigger
the submission of the form onchange of the first select so that you can
populate the second select based on the first's value over on the server
side and then redisplay the form.

To do it without any javascript you would need to use a second submit button
to do this, which the user would need to click after having entered a value
in the first field.

Hi,

We have two select boxes in an HTML form. Based on the option that the user
selects in the first box and some other considerations, the contents in the
second box get populated. Are there any reasonable means of doing this in
struts with minimal use of JavaScript ?

Thanks in advance
