java - Pagenavigation and value passing with afterburner fx in JavaFX? -

i'm using afterburner fx di-framework.
problem is, have "rootlayout" borderpane. on top menuebar, works , in center loaded other pane on startup. want able click on button, center-pane changes new view , want pass value new view/controller.

my main class:

@override public void start(stage primarystage) throws exception {     initinjector();      //borderpane     rootview appview = new rootview();     scene scene = new scene(appview.getview());     primarystage.settitle("personalplanung");     primarystage.setscene(scene);     primarystage.show(); } 

controller/presenter of root

public class rootpresenter implements initializable {  @fxml private anchorpane center;  /**  * initializes controller class.  */ @override public void initialize(url url, resourcebundle rb) {     mainview view = new mainview();     center.getchildren().add(view.getview()); }  //doesn't work because must static -> anchorpane can't static public void putcenter(fxmlview fxmlview) {     center.getchildren().add(fxmlview.getview()); } 

presenter of view want change , pass value (e.g. selected person)

public class mainpresenter implements initializable {  @inject personservice personservice;  /**  * initializes controller class.  */ @override public void initialize(url url, resourcebundle rb) {  }     /**  * pseudo display of persons  * should switch here persoview , pass values  * gets triggerd button click  */ @fxml private void handlepersonsoverview() {     personservice.all().foreach(person -> {         system.out.println(person.getvorname());     }); } 

all views empty extend fxmlview (is convention)

import com.airhacks.afterburner.views.fxmlview;  public class personview extends fxmlview{  } 

if understand structure correctly, think can solve viewmodel:

public class viewmodel {      private final objectproperty<node> mainview = new simpleobjectproperty(this, "mainview", null);     public objectproperty<node> mainviewproperty() {         return mainview ;     }     public final node getmainview() {         return mainview.get();     }     public final void setmainview(node mainview) {         this.mainview.set(mainview);     } } 

now inject viewmodel wherever need it. bind center of root view model's mainview property, , update mainview property other presenters:

public class rootpresenter {     @fxml      private borderpane root ; // think have this?     @fxml     private anchorpane center ; // possibly no longer need this?      @inject     private viewmodel viewmodel ;      public void initialize() {         root.centerproperty().bind(viewmodel.mainviewproperty());         mainview view = new mainview();         viewmodel.setmainview(view);     } } 

now presenter needs change center of root needs do:

public class somepresenter {      @inject     private viewmodel viewmodel ;      @fxml     public void somehandlermethod() {         someview someview = new someview();         viewmodel.setmainview(someview.getview());     } } 

to pass values new presenter, define appropriate properties , methods in presenter , invoke them when create new view:

public class mainpresenter {     private final objectproperty<person> person = new simpleobjectproperty<>(this, "person") ;     public objectproperty<person> personproperty() {         return person ;     }     public final person getperson() {         return person.get();     }     public final void setperson(person person) {         this.person.set(person);     }      public void initialize() {         // bind person needed ...         // other stuff before     }      // ... } 

and can do

mainview mainview = new mainview(); mainpresenter mainpresenter = (mainpresenter) mainview.getpresenter(); mainpresenter.setperson(selectedperson);
