Subject Re: Map-backed Forms and Struts Validator

Hi Derek,

from the ppt doc, it looks like validWhen is using a syntax that is 
designed for checking indexed properties. I haven't used it though.

I assume that it would handle nested beans as well, in accordance with 
the rest of the action form functionality. But again, I don't know.

Also it says you can't use validWhen until you upgrade to struts 1.2 or 
a nightly build.

I admit, it doesn't look hopeful. Have you tried a simple test case 
using the syntax like in the ppt doc?
