"Web and HTTP" feature problem

I am using SoapUi 3.6.1 pro for testing the website GUI. It is a new feature added in soapui.

I am browsing the website and recording the steps. There are some pages that take input from the user and use "http post" method for that form. Now when I am playing back the recorded test case, it fails to give the values to the form. The log shows that null is being passed.
Has anyone faced the similar problem?
Can someone provide any help?

Thanks,
Neeraj
