@FlowScoped annotation is for CDI only, so it will not work for JSF
managed beans. In your case, I believe the bean is instantiated but it
is not stored in any context, so once is created is discarded, giving
the impression that the bean is working but it is not.
In MyFaces it is possible to create a custom flow scope annotation for
other containers that works just like @FlowScoped, implementing
org.apache.myfaces.spi.FacesFlowProvider SPI interface. You are
already in CDI, so you don't need to bother about that.
I have seen @Named annotation working with Spring, so it is not
something specific for CDI, but @FlowScoped depends of CDI API.

Try in this way:
<p:menuitem value="Blah blah blah" outcome="flow1" />
If you put "/flow1" as outcome, the navigation algorithm will
interpret this as a normal navigation to a page (/flow1.xhtml), so the
flow scope will not be activated and the bean will not be instantiated
correctly. It should work without any changes in primefaces, because
the outcome should be calculated using
ConfigurableNavigationHandler.getNavigationCase(...).

Try it again, maybe the reason is that it seems you are inside the
flow but it is not. You can check if you are in the flow using
facesContext.getApplication().getFlowHandler().isActive(...).
