[Webtest] Cannot find inputs with a dot in the name

[Rajesh Menon]

Hi all,
I am running across an issue where if I have two forms
in my document and I select a form and use 
<setinputfield name="user.firstname" value="xyz"/>
webtest is unable to find the text field. Fields
without .'s are ok.

Any help would be great. I am stuck here now.
