how to use a select option with a property from the form bean?

[Roxie Rochat]

I would like to configure a form bean with a property that contains a
collection to be rendered as a select statement, but I can't get it to work.

If the options collection attribute is not specified, the docs say that you
can 
specify just the property:
"The value of this attribute is the name of a property of the
ActionForm bean associated with our form, which will return the collection."

What should this collection look like?  Can anyone point me at an example?

Thanks,
Roxie
