updating embedded views from cidu00B4s in a window when context change

I have a window W_Main in a Main-component M which embedds an interface view V_L. V_L contains 3 interface views from cid-implementating components (A-C) . the 3 cid´s are if_a - if_c. in the component of if_a (a1 or a2 ->dynamical) an attribute "value" is set and via the context of M shared to the other cid´s.

In a1 or a2 I am able to make an input in an inputfield which is bound to the context attribut "value". then I want to click a button and all three views should be updated. So the output in the views from B-C depend on the value input in A1 or A2.

how can I realise this?

My plan was simply make an outbound-plug from the view in a1 or a2 and link it to the inbound-plug from my main window W_Main which embedds the view V_L (which contains all 3 views a-c) but this doesn´t work.

what can I do? calling inbound-plugs in every embedded view via a outbound-plug from view in a1 or a2 is long winded I think?
