 <p>If I understood correctly you are trying to access a parent controller from a child controller. Here are some proposals ordered from noob to expert ;)</p> <ol> <li><p>The simplest approach would be to just use a global variable to provide reference to the controller you need - not recommended.</p></li> <li><p>Give your parent view an id and call a method on it's controller like this:</p> <p>sap.ui.getCore().byId("parentViewId").getController().method();</p></li> <li><p>You can directly call a controllers method like this:</p> <p>sap.ui.controller("namespace.Controllername").method();</p></li> <li><p>I would highly recommend a more decoupled way of communication between controllers (or application components in general) using the <a href="https://sapui5.hana.ondemand.com/sdk/#docs/api/symbols/sap.ui.core.EventBus.html" rel="nofollow">sap.ui.core.EventBus</a>. It implements a pattern known as Event or Message Bus and imho really rocks ;)</p></li> </ol> <p>GL Chris</p>
