Passing parameters through URL in ADF Application with UIShell

Question

Hi,
JDeveloper Studio Edition Version 11.1.1.6.0
The UI in our application is developed with UIShell pageTemplate.
We have a Home page created with PageTemplace "UIShell.jspx" and this page is placed as a view in adfc-config.xml (the Unbounded Task Flow).
The other pages for our application are created using Page Fragments and these pages are called from Home_taskmenu.xml through Bounded task flows.
With this setting, the URL(after SignIn) will look like,
http://localhost:7101/OperationalPlanning/faces/Home?_afrWindowMode=0&_adf.no-new-window-redirect=true&_afrLoop=6811862222491857&_adf.ctrl-state=29wus7giw_19
We have a requirement to build the URL which should open a Page Fragment directly after Signing In to the application. And we have a id to be passed as a parameter, so it should open the page fragment with the details based on the id value that we pass.
The parameters are already registered in the Bounded Task Flow(which has the page fragment) and I could open in the "localArea" using a link in the Home Page.
Now, I want to directly launch the Bounded task flow by passing a parameter, so that it opens the Page Fragment as a tab once we signIn.
Let me know if there is any solution for this requirement.
If there is any document to follow for this kind of requirement in an application which is created using the UIShell, please let me know.
Thanks,
Tamil

hi Frank,
Thanks for the response. We followed your suggestion and managed to capture URL parameters in afterPhase(LifeCycle.PREPARE_MODEL) and save parameters to ViewScope.
Then in beforePhase(LifeCycle.PREPARE_RENDER), we retrieve parameters back and invoke FndUIController.openMainTask method to launch the correponding taskflow but nothing happens.
public static void openTaskflowOnNewTab(String taskflowId) {
try {
FacesContext fc = FacesContext.getCurrentInstance();
ELContext elc = fc.getELContext();
ExpressionFactory ef = fc.getApplication().getExpressionFactory();
ValueExpression valExp = ef.createValueExpression(elc,"#{bindings.openMainTask}",Object.class);
JUCtrlActionBinding methodBinding = (JUCtrlActionBinding)valExp.getValue(elc);
Map params = methodBinding.getParamsMap();
params.put("label", "Some Title");
params.put("taskFlowId", taskflowId);
params.put("reuseInstance", true);
methodBinding.invoke();
} catch (Exception e) {
e.printStackTrace();
To prove that this method works, we create a UI button on the page (which binds this method in PageDef.xml), and associate this method to onclick event. At runtime after page is opened, clicking on the button does launch the taskflow on new tab successfully.
Do you happen to know what I do wrong in the beforePhase() method?
Thanks
