ArrayList and #foreach

[sabatier <fl...@tcd.ie>]

Hi I have an ArrayList of checkbox values from a form. The ArrayList is
populated in the following way in a java servlet (where 'rw' is the
ArrayList):

if ( item.isFormField() && item.getFieldName().equalsIgnoreCase("rw")) {
                rw.add(item.getString());
            }

.
.
.
context.put("rw", rw);

I want to put these values into a velocity/xml template using the #foreach
loop.
eg. 

#foreach( $item in $rw)
         $item
#end

This isn't working however. Could someone tell me where I'm going wrong?
Any help would be appreciated.

Can you tell us more? What is happening exactly?

You can print usefull debugging informations in VTL, like:

the arraylist: $rw ## should display sthing like "{ item1 item2 }"

its length: $rw.size()

#foreach($item in $rw)
	found class $item.class.name
#end

etc...
