Re: [Springframework-developer] Web Flow - Sub Flows

[Erwin V. <erw...@er...>]

The code that is in the sandbox right now explictly prevents a state from 
transitioning to itself. The test is in the FlowSession.setCurrentState() 
method:

if (this.currentState != null) {
   if (this.currentState.equals(newState)) {
      throw new IllegalArgumentException("The current state is already set 
to '" + newState + "' -- this should not happen!");
   }
}

Having a state transition to itself is dangerous business since you could 
end up in an infinite loop!

Could you explain a bit more what you're trying to do? Why do you want to 
keep restarting the subflow in a loop?
