If I have something like this in my document:

<input type="hidden" name="customer.id" id="customer.id"/>

With version 1.1.x I was able to do this: $("#customer.id")

In version 1.2.x it returns nothing. However $("#customerid") works.

This is critical for people using JQuery with Java and the Stripes framework, since all inputs are named with a dot in them.
