how-to exchanging data between 2 components (sender-receiver) ?

[Former Member]

Dear all,

I've seen some topics on how to exchange parameters between 2 components (but embedded one). What I would like to achieve is to exchange parameters/values between 2 components in a same web-dynpro application.

For example, component 1 expects user-input, on a go-button, this closes component 1, starts component 2 and passes the input.

The example in the help is 2 views in the same component, but I want 2 components and each has 1 view without embedding the one in the other (using viewsets to display)...

Any ideas how to get this working (interfaces, plugs, ... )

any help is welcome !

regards,

Hi Stefaan,

one possibility is to use an outbound plug of the used Sender component's interface view for transporting:

1. The on-go button fires the outbound plug with at least one parameter representing the payload.

2. The receiver component's interface view which should be "started" by the go-action has a similar inbound plug (same parameter signature).

3. The component, which uses the interface views of sender and receiver in it's view assembly defines a link between the outbound plug of sender and inbound plug of receiver.

Hope that helps.

Hi Stefaan,

Maybe you can use two custom controllers and call one of the controllers as a used controller from the other one.
