Unbounded task flow with pageflowscope

Question

Hi,
In my application, I have create unbounded task flow for each menu. For each menu task flow I have created a pageFlowscope bean. When I try to use this bean in any request scoped bean called from within the UTF, I get the pageFlowSCoped bean instance as null.
PageFlowScoped bean declared in UTF:
<managed-bean id="__3">
<managed-bean-name>uiManager</managed-bean-name>
<managed-bean-class>oracle.test.UIManager</managed-bean-class>
<managed-bean-scope>pageFlow</managed-bean-scope>
</managed-bean>
This UTF has a jsf page which consists of few BTF’s. In one of these BTF, I have a fragment page for which I have used request scoped bean. In this bean, the instance of uiManager is coming as null.
BTF where requestScoped bean declared:
<managed-bean id="__1">
<managed-bean-name>EmployeePage</managed-bean-name>
<managed-bean-class>oracle.test.employee.EmployeePage </managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property id="__13">
<property-name> uiManager </property-name>
<property-class> oracle.test.UIManager </property-class>
<value>#{pageFlowScope. uiManager }</value>
</managed-property>
Inside EmployeePage.java:
private UIManager uiManager;
public void setUiManager(UIManager uiManager) {
this.uiManager = uiManager;
public UIManager getUiManager() {
return uiManager;
Can anyone please let me know what is wrong with this?
Thanks in advance.

Hi,
This UTF has a jsf page which consists of few BTF’s. In one of these BTF, I have a fragment page for which I have used request scoped bean. In this bean, the instance of uiManager is coming as null.Yes it will because each taskflow has its own flow. So when you refer pageFlowScope inside BTF the framework will look in its own flow i.e in BTF to find uiManager hence you get null. Which is present in page flow,
So in that case what you can do is have a inputParameter in BTF that has variable called uiManager of type UIManager.
when dragging and dropping it in page of UTF specify the inputparameter as #{pageFlowScope.uiManager} what you have mentioned as
<managed-bean id="__3">
<managed-bean-name>uiManager</managed-bean-name>
<managed-bean-class>oracle.test.UIManager</managed-bean-class>
<managed-bean-scope>pageFlow</managed-bean-scope>
</managed-bean>And thus you can access the uiManager the way you except.
