Instantiating the taskflow instances at runtime

Question

We are trying to develop the MDI application using ADF. When user clicks on navigation item a new showDetailItem should be added to pannelTab. The showDetailItem should contain the taskflow within a region. For adding the taskflow as a region , navigationItem actionListener has the following code.
public void myActionListener(ActionEvent actionEvent) {
// Add event code here...
RichShowDetailItem tab = new RichShowDetailItem();
tab.setText("8051");
RichRegion r = new RichRegion();
RegionModel model = (RegionModel)ELHandler.get("#{bindings.taskflowdefinition1.regionModel}");
if(model!=null)
System.out.println("Model found .....");
r.setRegionModel(model);
r.setValue(model);
r.setVisible(true);
r.setRendered(true);
r.setImmediate(true);
tab.getChildren().add(r);
if(pt2!=null){
System.out.println("Just before adding showDetailItem ........");
pt2.getChildren().add(tab);
}else
System.out.println("pt2 is NULL .....");
when we execute the application no error seen on server console and new tab gets added on the screen. But the region is not renderred on the browser. We are unable to instantiate taskflow instance programatically.
Please advice.

Hi,
its a known limitation that this doesn't work yet. The ADF Region must be added at designtime. You can experiment with dynamic regions in opposite to static regions, using an approach outlined here
insert a region programatically
