Yeah, you can chalk this one up as a "duh" moment for me. I'm using the
Db4o object database to save my objects, and it was erroring out when I was
trying to save an ArrayList<String> retrieved from the form, (but Struts2
was returning an XWorkList instead). Struts is just doing what it should
be, and I think my Db4o code is in error.
Thanks for the replies...
