Hello everybody.

I am having trouble to find the best approach to maintain a communication beetwen two controllers which are running at the same time.

I have two controllers (A and B).

The A.zul file:

<window>
  //Other components
      <tabpanel>
        <include src="/views/B.zul"/>
      </tabpanel>
    </tabpanels>
  </tabbox>
</window>

The B.zul file:

<div id="divB" apply="pkg.B">
  <button onClick="divB$composer.doSomething();"/>
</div>

A.java:

class A extends GenericForwardComposer {
  public void doSomethigOnButtonInBControllerClicked() {
    // Do something when the button in the B controller was clicked.
  }
}

B.java:

class B extends GenericForwardComposer {
  public void doSomething() {
    // Call doSomethigOnButtonInBControllerClicked of A
  }
}

B is included by others controllers, which means it has to warn his "parent" without know who is it.

What is the best approach in this case?

Thanks in advance.
