There is some example.

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
