Help with R2D2W... Again!

Hello, all!


I’ve been wrestling Ponder’s R2D2W for the last couple of days and still haven’t got my application to run. I don’t remember it being this difficult  last time — it’s been quite a long time, so there’s a lot I can’t remember! ;-)

I have my model in a framework and, when the application starts for the first time, the tables are created automatically by the migrations. I can attest that by looking at the database with pgAdmin3.

When it try to load the app on a browser, it gives an internal server error right away. Eclipse’s console shows:

Two more errors are shown when the app tries to show the exception: "Exception while trying to report exception!” and "Exception occurred while responding to client”. Both stack traces seems to break in er.auth.ERStageManager.wakeActor(), same line.

In my R2D2W app, I have this rule in d2w.d2wmodel:

100 : *true* => userEntity = "Usuario" [com.webobjects.directtoweb.EntityAssignment]

I am sure it’s a silly little details that I’m overlooking, but not sure what.


Cheers,
Flavio
