Interesting problem...
Using textfield as an example, the template (eg. text.ftl) takes the
literal name attribute from <s:textfield> and writes it straight to the
html. You could create your own theme that replaces the '.' with a
different character in the html. You could then write your own
interceptor that converts the name attributes back to the syntax
expected by the parameters interceptors before it's executed. This would
let you use OGNL in the JSP, but give you your javascript friendly names.
You'd have to check that none of the S2/dojo javascript uses names
instead of Ids though. And this will confuse IDE syntax highlighting. Yuk...
I guess it would be nicer if you could write a javascript function
getElementByName('document.addressForm.address.street') that knows
'address.street' is the name of an input because document.addressForm is
a form element. That seems do-able.
