I am running a Seam 2.1 with jboss 4.2 and jbpm 3.2.2.

I altered the hibernate mapping of the class Toto. I included one new attribute called userDev, with the following getter:
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "id_user_developer", nullable = true, insertable = false, updatable = false)
    public User getUserDev() {
        return userDev;

The data base structure was not modified, and when a Toto object is persisted, the column id_user_developer is not altered in the data base.

The server starts ok, and I can normally create, edit and delete new Toto instances, as well as perform jbpm tasks on it.

However, if I try to perform a jbpm task on Toto objects that were created before the mapping modification, the jbpm task do not succed.

I think the problem is related to the jbpm tables, that weren't updated according the mapping modification.

Anyone have any idea on how can I solve this issue for the Toto instances created before the mapping modification?

Thanks a lot.
