Help on adf taskflow scope

Question

Hi,
I am using JDeveloper 11.1.1.4 and ADF-BC in my application.
In one of my modules,I have the following scenario.
I have a bounded task flow and a page fragment[ex: mainTabs.jsff] on it.I have registered a backing bean with scope pageFlow and some name[ex:mainTabsBean].
In the mainTabs.jsff file , I have four tabs.[I have to show separate table in each tab] and two buttons Save and Cancel.
So I created 4 taskfows with corresponding jsff files and in all the 4 taskflows, I have registered the same backing bean as above and with same scope[scope pageFlow  and  name 'mainTabsBean']
I dragged and dropped these taskflows as regions in the mainTabs.jsff in the corresponding showDetailItem tags for tabs.
I want to have the same instance of 'mainTabsBean' being used in the mainTabs.jsff as well as the tab pages.
But the instances are coming differently when accessed from mainTabs.jsff-->Save button and subTab.jsff --> some action.
Please advice where am I doing wrong or which scope to use in this case.
Regards,
Praveen

Hi,
First add all beans to taskFlow as managedBeans,then keep one bean as a main bean(say MainBean) and add other beans as manageBean property to MainBean.and in MainBean you can access all subBeans as follows
class MainBean {
SubBean subBean;//define setters and getters
SubBean2 subBean2;//define setters and getters
SubBean3 subBean3;//define setters and getters
*manageBean property* name should same as above define instances names(subBean,subBean2,subBean3...)
