Download updated sample - ADFIntegrationRegions3.zip, based on my previous post. Main change comparing to previous post sample - there is ADF Task Flow call from Locations to Departments:
All separate applications are deployed and assembled into one main application, same as it was described before. Only one difference now - first Dynamic Region (Locations) contains Departments buttons, it will navigate to second Dynamic Region (Departments) directly:
User can click on Departments button:
And here we go - Departments Dynamic Region is opened, menu item selection is synchronized as well:
Well, how to implement this? There is a very good hint in Frank Nimphius and Lynn Munsinger book (Building RIAs w/ Oracle ADF) on page #201 RegionNavigationListener. We can declare it for af:region:
And listen for navigation from Locations to Departments, if such navigation happens - we reset menu and switch Dynamic Region (Departments) as current:
Its how it works.

Hello Andrejus,
Thank you very much for your very useful ADF examples. The examples are very handy to learn many key concepts.
My client has the following requirement. They would like to use region+dynamic task flows concept to bring in different task flows based on some condition.
How one can pass parameters to each of these dynamically instantiated task flows in a region?
Appreciate your feedback,
Thanks,
Tiah
Hi Tiah,
You can enable this programatically, from the same dynamic task flow bean class. It should work.

Hi Andrejus,
Thanks for the post. I am trying to work on a simpler than this. But not able to get it. I want to tell the button action from one region to another region. First region has two buttons and second region should display a screen based on the selection of the button in the first region.
I am using the following after raising the contextual event on the button in the first region.
public void receiveButtonEvent (ActionEvent actionEvent03){
RichCommandButton rcb = (RichCommandButton)actionEvent03.getComponent();
System.out.println("Action Text = "+rcb.getText());
String prAction =
}
I am not able to get the action. Is this correct?
May be you are trying to implement it too complex. Why not to use just Input Parameter for fragment and to do PPR on that fragment?
Andrejus
