ADF Region Dynamic Taskflows integration Dynamic Parameters passing

Hi,

This is Tiah. Recently I started learning ADF Task flows and using them dynamically inside regions. When I came across a requirement to pass different sets of parameters to different task flows that gets instantiated within a region, I found no concrete example. So sort of tried the information given in Fusion Guide and able to work with passing different sets of parameters to different task flows.

This is a simple example where I have two task flows first and second. First task flow has one parameter "Param1" and the Second task flow has two parameters "Param1" & "Param2". I used the bean to create the param maps when I am switching the task flows.

The code is given below... I will soon upload my sample example

I will be enhancing it with return params as well soon.

Hope it will be useful,
Thanks,
Tiah
