    Problems with "hibernate.hbm2ddl.auto" property set to updat

    Toni Beckman Novice

      Hi,

      I noticed that my webapp stops working, when I change the "hibernate.hbm2ddl.auto" property of my persitence.xml file from "create-drop" to "update".

      This used to work before and now I get the following exceptions, when I try to retrieve a set of entities to populate a DataModel for rendering a JSF Table in a JSP page:

      Caused by: javax.faces.el.EvaluationException: Bean: $Proxy663, property: dataModel
      ... 56 more
      Caused by: javax.ejb.EJBTransactionRolledbackException:
      ... 61 more
      Caused by: java.lang.ClassCastException: java.lang.String

      If I set the property to "create-drop" I can use the webapplication an get NO errors? Does anybody know what could be the cause?
