I'm confused...If I had a User object with 5 out of 10 members that I wanted
to edit then I'd have these sorts of ognl: bindings to the field values:
<input type="@TextField" value="ognl:user.firstName" />
Then my POJO would only have the 5 of 10 values I'm mucking with updated. Am
I being retarded or did this answer your question?
