And in that spirit:
<struts-html:multibox property="subscriptions"
><struts-bean:write name="_bean" property="code"/></struts-html:multibox>
<struts-bean:write name="_bean" property="description"/><br>
</struts-logic:iterate>
is 4 lines of code
plus the 3 lines of code you'll need in reset. Plus the i18n ability with no
additional codeing.
Not to mention being able to hand off the code to the web design folks and have
them easily make things purty.
