more seam resolver issues - how to handle a list that isn't
I am trying to build a simple, two page app that performs a login and if valid, proceeds to the second form that has search fields across the top and displays any valid records below the form (if any).
The login works fine and forwards to the 2nd page. I would expect seam not to find anything in the "conversation" (rather than sesssion) since the user hasn't entered anything. But when I do type in something and press Search, I get:

I've got the seam.properties file in the root of the EJB archive. This is working since the user login page was able to resolve the class to authenticate the user against.
Here's my quandry:
The concept of a DpsDriver (class) is an Entity since they exist in a table. That same object should store the users search parameters (private DpsDriver dpsDriverCriteria;) and of course a List of them is what should be returned from the database. I have no way of knowing if the following class and page would even work since seam cannot find the classes.
According to the tutorial on pages 13 and 14, the form references the @DataModel and @DataModelSelection properties and NOT the encompassing class:
this:
<td class="formFieldColumn"><h:inputText id="driverName" value="#{dpsDriverCriteria.DriverName}"/></td>
not this:
<td class="formFieldColumn"><h:inputText id="driverName" value="#{dpsDriversList[dpsDriverCriteria].DriverName}"/></td>
I'm sure I have some aspect of the syntax wrong up there. But I've tried every variation I could think of.
Seam is complaining that it cannot find an object - when the name its looking for is property of an object. What have I setup wrong?!

Please help! I've wasted nearly two weeks trying to get this to work.
