Attempting to create a D2W front end for my ERREST app

Greetings:

I am attempting to create a quick and easy D2W front end for my Rest app built using ERRest.  I have the EOModel and eo classes in their own framework, while the rest of the . . . er . . . rest stuff is in it's own project which links the EO framework and seems to work fine with no db issues.  

I therefore created a new Wonder D2W application, and linked the EO framework and ran it.  (it's using the ERModern default skin for now, though I'll likely change that to a copied skin later).  The db is MySQL, and works fine for the rest app.

When I run the plain vanilla, out of the box wonder d2w app, it shows the expected front page with the appropriate entities, but when I search for something, I get this exception.  Presumably there is something else I was supposed to do but forgot.
