Recently I have faced a problem, when was trying to navigate to ADF Task Flow Call activity. The problem was, that I was initiating navigation from inside the region and navigation flow was defined not in bounded region ADF Task Flow, but inside parent bounded page ADF Task Flow. This means, navigation outcome from parent ADF Task Flow was simply invisible for button I have created inside region. But as usual in most of the cases, ADF provides very elegant solution to solve problem of external navigation from inside the region
This depicts in this videos please watch.-
