And since the action is still in the Flow, it still refers to the old, outdated version of OR
Or, to rephrase the question, I have a test that calls an other action. I delete the action from the test, but in the Test Flow Window/Action Toolbar it is still visible, and still calls the "old" code.
You cannot just delete the action call code in the expert view. If your using QTP 8.2, there is a External Action Call Modifier utility in QT Plus where this can be fixed. I'm sure there is something similar in QTP 9.
