Subject Re: checkbox widget with datatype vector
Date Sun, 23 Jul 2006 16:49:12 GMT
is there a way I can build my list from accesing the required order class I
use in selection-list? In my jx I do:

<jx:forEach var="orderitem" items="${neworder.getOrderItems()}">

and then pull out the id I want in the checkbox as so:

<fi:styling value="${orderitem.getID()}" type="checkbox"/>

So would I be able to do:

selection-list src="neworder.getOrderItems().get()" ? And if so how would
the selection-list know how to iterate through the object to pull out all
orderitem id's?
