> This problem only occurs when the trace is specified. The DebugUtils tries to
> print out the ViewMap and a new storage is created during this process.
> Is seems like there are two ViewMap (ViewScopeCDIMap) used since the storage
> for the cleared view is marked as deactivated and this other one created a
> new storage object?
