    <p>WHAT I HAVE is a standard JavaFX application: <code>Main.java, MainController.java &amp; main.fxml</code>. To add custom component, I created <code>CustomComponentController.java</code> and <code>custom_component_controller.fxml</code>.</p> <p>PROBLEM is that in <code>CustomComponentController</code> methods I need to reference other methods and standard components from <code>MenuController</code>. I add <code>public static MainController mc;</code> to <code>MainController</code> class body, so that it can be seen from <code>CustomComponentController</code> (<code>MainController.mc.neededMethod()</code>). Then I try to pass everything to it in <code>MainController.initialize()</code> method (<code>mc = this;</code>) - when debugging this breakpoint, I see <code>this</code> full of components instances, but <code>mc</code> remains with null components afterwards.</p> <p>QUESTION is how to reference the running instance of <code>MainController</code> to use its components and methods in other classes and to crossreference different custom components from each other? How to clean <code>MainController</code> code from event handlers and assistance methods of components by moving it all to component's own class?</p> <p>I tried the following approaches, but found no way to make them work without errors:</p> <p><a href="https://stackoverflow.com/questions/10751271/accessing-fxml-controller-class">Accessing FXML controller class</a></p> <p><a href="https://stackoverflow.com/questions/10240471/how-can-i-access-a-controller-class-in-javafx-2-0">How can I access a Controller class in JavaFx 2.0?</a></p> <p><a href="https://stackoverflow.com/questions/10107829/javafx-2-0-fxml-updating-scene-values-from-a-different-task/10108788#10108788">JavaFX 2.0 + FXML.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
