    Exception getting value of property resultList of base of ty

    sstrenn Newbie

      I am trying out seam 1.1.6 and jboss 4.0.5 ejb. I setup a project with seam-gen that accesses a simple little mysql database with users and blogs. After I call seam generate-entities, and restart seam, I get the following error trace upon accessing the users page. Any ideas as to what is wrong? BTW - same thing happens w/mysql.
