Changing requestscoped to sessionscoped gives an error - jsf

Question

When I changed my managedbean from requestscoped to sessionscoped it gives this error when deploying the app. Can anyone explain what is happening?
Does the ejb injection fails in the postconstruct? Also when changing it back to requestscoped I get the same error. When restarting NetBeans the requestscoped works.

Answer 1

It always depends on the scope of the objects you inject into your bean.
If one the following objects you inject: EmployeeFacade, CompanyFacade or DeviceFacade has a smaller scope, it will fail. In other words, you can only inject a bean with the same or a higher scope. I never tried this: request scoped property in session scoped JSF bean but it may help you out if you want to inject a smaller scoped object.
