Dora Rajappan commented on MYFACES-4127:
----------------------------------------
Myfaces CDI integration to route the call via
DefaultContextualInstanceStrategy.getIfExists rather than via
DefaultContextualInstanceStrategy.get to show the ContextNotActiveException.
Throwing ContextNotActiveException from FlowHandlerImpl (public Flow
getCurrentFlow(FacesContext context)) when window is null fails lifecycle
execute testcase. Hence not an option.
> Unexpected exception thrown when FlowMap is injected on a RequestScoped bean

> When @FlowMap is injected on a RequestScoped bean, and you try to use that
> object (which should be null since we are not inside of a flow), an
> unexpected exception is thrown. This was noted after JIRA issue:
