Hi, now it is hopefully clear to me. You have an object 'budgetOverview' which is managed by seam, due to the @name annotation . At some stage in your workflow an object called budgetOverview is created (new ...) This object is NOT managed by seam. And you are outjecting this object into the same scope as the seam managed object resides in. So the datamodel can not be outjected, since you are not having a managed object in the scope. You should not create, with new, the budgetOverview object. Try to inject this bean into expresscalculator. If you have questions abourt the examples or documentation do not hesitate to ask here.
