Hi,

In certain cases my HTML form controls need to map to second level
Java object properties. For example a form for inputing a person's
name, position, and contact info may have HTML text boxes name,
address and phone number, but these may map to POJO in backend as
person.name, person.contact.address and person.contact.phone.  Ideally
I want my HTML input controls to have ids like "name",
"contact.address" and "contact.phone" and let DWR's getValues() method
construct JSON object
{
        name : "John Smith",
        contact {  address : "1234 Hollywood Ave" , phone "88774542" }
}

and send that to server to invoke Java method
   createPerson(Person p)

So I patched util.js to make setValues() , getValues() aware of the
special dot notation for input ids.  Here is the diff for
dwr-1.1.beta3 source. Please note this patch works for my app but is
not thourought tested yet.
