[collective.easyform] default field values from request

Is there a way with collective.easyform to use request parameters as default values for form input fields?
This was possible with PloneFormGen but this feature does not seem to exit with collective.easyform..or something I am missing?

This works for me when using the exact field name like ?form.widgets.replyto=xxx@yyy.com ... version 2.1.0rc1

aha...I was missing the form.widgets. part.
