FYI:  velocity-tools now has a working TilesTool that will be included in our
next release (1.1).  :)

the key here is to remember that forms are stored in the request (or session
if they're session-scoped) under their own names (as defined in your
struts-config), and all request/session/application attributes are
automatically exposed to your templates.  this means that you just reference
your multiple forms by their names instead of through the FormTool.  the
FormTool's getBean() method is really just there for the convenience of not
having to remember the name of the form associated with the current action
mapping.

basically, instead of using $form.bean.someField  do  $MyFooForm.someField

sounds fine.  if there's something i've missed or you have other questions,
just ask!
