Hi Thiago, thanks for the quick reply, I'd already seen the official tapestry property expressions page but as there's no examples given there I was hoping there was something else buried in one of the wiki pages?
I'll take your advise and move this logic to the java class, I'm going to have a lot of helper methods for the logic that was attached to the various fields on my form, but I guess I can't be avoided.
