[Wonder-disc] FrontBasePlugIn exception

[Ricardo J. P. <rp...@ma...>]

I created a little Wonder application... I created a database in  
Frontbase.  I'm doing migrations.  The application launches and  
creates all the tables in the database.  Everything seems perfect.

However the following simple code is generating an exception and I  
can't figure out yet what's going on:

			EOQualifier qual =  
Usuario.NOMBRE.eq(username).and(Usuario.CONTRASENA.eq(password));
			EOFetchSpecification fs = new  
EOFetchSpecification(Usuario.ENTITY_NAME, qual, null);
			session().defaultEditingContext().objectsWithFetchSpecification(fs);

Here's the exception:

Here's the eomodel:




And here's what the table looks like in FrontBaseManager:
