Hi,

Don't know if i understood your Ques Correctly, but as per my knowledge and understanding, u want to transfer data between 3 components, without doing context mapping.

Steps:

A : With Click of a button say( go to Next), you can fire a outbound plug. This outbound plug has to be of the window, and with this plug you can pass as many parameters as required from one window to a diff window/view of a separate Component .

B: Make an inbound plug of the view of ur 2nd component and make a navigation link. With this you would be able to get the values passed by the 1st window. This View may/or may not be the default view of the 2nd window.

C:You have to declare the Component Usage of ur 2nd component in 1st comp.

Hope this helps.

Cheers.

Hi, Phil,

I think you misunderstand what's means of li pei.

his means is:

A is a component for logon page.

B is one component for the main page.

C is one component for the error page.

ACTION:

1.

Type userid and password in the textinput in the logon page("A"),

2.

Then the user login the next page("B" or "C").

Question:

How do you transfer the context node of A to next page("B" or "C"), excepting embed the component("B" or "C") TO A -

---

because we don't want to remapping 2 context node(of B AND C) to A?

I and Li Pei try to embed the A to B and C component, and create mapping separatly between A and B,C, but we don't get the context node value of A from B or C. That is,

A invoke B or C. A uses views of B or C, and this B or C views use context nodes (by mapping) from A. This is a reciprocal component usage. Is this allowed?

But i want to create the interface once, so i use the component 1 as interface.

How do i use it to transport parameters to component 2 and 3 ?

Hi Pei Li,

If I undertood the question,

how can 2 WDCs call each other.

It is done via Method calls outbound and method event handlers inbound.

In the 2nd WDC, register an EVENT . The event can have parameters.

Fire this event nad pass any parameters appropriate.

The first component has a method of type event handler.

The component usage must first be declared in properties tab.

The method in component 1 now gets control after the event is fired.

In summary, the COMPONENT USAGE

is METHOD calls ->

and Method Event handlers <-

regards

Phil
