This is exactly the scenario of the testcase I shared with you, and it
does work. The automated test asserts that it works. Here's the flow
stack:
flow2
flow1
root
We are in flow2. We activate "exit2". It returns "exit1". Because the
system is specified to be operating in return mode during the time when
getNavigationCase() is being processed as a result of the render request
from the OutcomeTarget renderer, "exit1" is found within flow1. This
will look for a flow node named "mainpage".
Now, that "mainpage" *must* be within flow1. If it's not within flow1,
it will be a navigation that doesn't resolve correctly, which means we
will stay on the same page.
Leonardo, I think we should have a google hangout where I can step you
through the code. Will that work? It will have to be the week of March
11th because I am on vacation on from the 5th, returning to work on the
11th.
