Hello Gavin.

When getInstance is called and there is no Id in any context, session.get is not callable. So the if statement should ensure the pre condition for session.get.

My object which i want to manage is choosen by the user. When the user select the object i set the Id in the appropriate context.
In my app i do not know when a user has the selected the object. So it is possible that i reference this object when no id is set.

Concrete: On each of my pages i have to display the project number of the bazProject the user works on. But as long as the user has not choosen a project, the bazProjectID id will be null.
