There was a message on the forum a long time ago
(http://sourceforge.net/forum/message.php?msg_id=1997848) where someone
was asking the same thing.
 
Anybody, please correct me if I'm wrong, but I don't believe this is
possible using the current ServletRequestDataBinder and
BaseCommandController.
 
To support lists in combination with PropertyEditors, I once used a
ListDataBinder (extending ServletRequestDataBinder). With this
databinder it is possible to iterate over the objects in the list and
rendering fields/properties using the propertyeditors that are
registered... Quite straightforward. However, this only does the
rendering of properties using propertyeditors. How to do binding, I
don't know (yet). I'll attach the source of the ListDataBinder, which is
to instantiated in a AbstractListController. The fetchList-method in the
ListController class, atcually fetches the list (which is used in the
ListDataBinder)...
 
Example of usage:
<!-- the iterator from the ListDataBinder exposes the command object -->
<c:forEach items="binder-command-attribute-whatever" item="bla">
    <!-- the bind tag binds editors and values and stuff for the current
element in the collection -->
    <spring:bind path="propertyToRender">
        <:out value="${status.value}"/>
    </spring:bind>
</c:forEach>
 
have to go... I'll get back to you later...
 
cheers,
 
Alef

Hi everybody. I have one question, if any one has a quick answer :-)
What would be the best way to "bind" html data into a collection of
objects? 

Let's say I have an html table in the form, each row representing a
model/command object. When submitting this form to a Controller, I would
like to bind the values from the html table into a Collection of
model/command objects. What would be the best way to do that?

Thanks, 
Dmitriy. 

P.S. 

I believe there was a message about this issue on the list, but I'm to
lazy to search for it ;-)
