Reg: Task flow

Question

Hi,
I need to know answers for the following two questions. I have developed application using ADF BC with dynamic UI tab shell. In my task flow 1, i have a jsff file and another task flow call.
My first question is,
I have a button in my task flow's jsff file. On clicking this button, I need to trigger a click action of Main page link. To obtain this, i used two methods in my backing bean.
1. MainBean mainBean = new MainBean();
RichCommandLink link = mainBean.getMainPage_link();
this link returns null.
2. I have extended MainBean in my backin bean and i created a method in MainBean then i called that method in my backing bean. The code of MainBean method is given below.
FacesContext context = FacesContext.getCurrentInstance();
RichCommandLink link = this.getMainPage_link();
String clientId = link.getClientId(context);
ExtendedRenderKitService service = Service.getRenderKitService(context,
ExtendedRenderKitService.class);
service.addScript(context,
"var exportCmd = AdfPage.PAGE.findComponentByAbsoluteId('"
+ clientId .toString() + "');"
+ "AdfActionEvent.queue(exportCmd, true);");
here also the link returns null.
how to trigger this action?
My second question is,
In my task flow, from jsff page I need to get whether the another task flow call is dirty or not.
How to get the dirtyness of the another task flow in my jsff page?
Thanks in advance.

Hi,
If you get MainBean mainBean = new MainBean(); mainBean is a new instance, get current bean instance instead create new one
