How do I prepopulate a view?

I've got a view-state I'm displaying with an attached bean. I'd like the view's fields to be pre-populated with data from the database. The user can then edit the fields and submit their changes. I'm having a lot of trouble getting the bean pre-populated, though. Here's what I'm trying; does anybody see what I should be doing differently?

Thanks,
Eric

Code:

---

<view-state id="updateUserInfoView" view="updateUserInfoView" model="userInfoBean">
        <on-entry>
            <set name="viewScope.username" value="flowScope.principal.id" />
            <evaluate expression="updateUserInfoAction.current(viewScope.username)"
                      result="flowScope.userInfoBean"/>
        </on-entry>
        <transition on="submit" to="updateUserInfo"/>
    </view-state>
