i have question tableview element in javafx.

when try use , add columns it, works fine, if set static (need access stage) columns not appearing @ all.

my code looks (extracts):

@fxml private static tableview<datensatz> table = new tableview();  @override public void initialize(url url, resourcebundle rb) { erstelletabelle(); }  private static void erstelletabelle() {     tablecolumn namecolumn = new tablecolumn("name");     namecolumn.setcellvaluefactory(new propertyvaluefactory<>("name"));      tablecolumn handynrcolumn = new tablecolumn("handynummer");     handynrcolumn.setcellvaluefactory(new propertyvaluefactory<>("handynummer"));      tablecolumn rechnungsdatumcolumn = new tablecolumn("rechnungsdatum");     rechnungsdatumcolumn.setcellvaluefactory(new propertyvaluefactory<>("rechnungsdatum"));      tablecolumn abrechnungsbeginncolumn = new tablecolumn("abrechnungsbeginn");     abrechnungsbeginncolumn.setcellvaluefactory(new propertyvaluefactory<>("von"));      tablecolumn abrechnungsendecolumn = new tablecolumn("abrechnungsende");     abrechnungsendecolumn.setcellvaluefactory(new propertyvaluefactory<>("bis"));      tablecolumn rechnungsnummercolumn = new tablecolumn("rechnungsnummer");     rechnungsnummercolumn.setcellvaluefactory(new propertyvaluefactory<>("rechnungsnummer"));      tablecolumn betragcolumn = new tablecolumn("betrag");     betragcolumn.setcellvaluefactory(new propertyvaluefactory<>("betrag"));      tablecolumn kostenstellecolumn = new tablecolumn("kostenstelle");     kostenstellecolumn.setcellvaluefactory(new propertyvaluefactory<>                                ("kostenstelle"));      tablecolumn telefonkostencolumn = new tablecolumn("telefon-kosten");     telefonkostencolumn.setcellvaluefactory(new propertyvaluefactory<>("telefon"));      tablecolumn smskostencolumn = new tablecolumn("sms-kosten");     smskostencolumn.setcellvaluefactory(new propertyvaluefactory<>("sms"));      tablecolumn internetkostencolumn = new tablecolumn("internet-kosten");     internetkostencolumn.setcellvaluefactory(new propertyvaluefactory<>("internet"));      tablecolumn vertragsdetailscolumn = new tablecolumn("vertragsdetails");     vertragsdetailscolumn.setcellvaluefactory(new propertyvaluefactory<>("details"));     vertragsdetailscolumn.setminwidth(100);      table.getcolumns().addall(             namecolumn,             handynrcolumn,             rechnungsdatumcolumn,             abrechnungsbeginncolumn,             abrechnungsendecolumn,             rechnungsnummercolumn,             betragcolumn,             kostenstellecolumn,             telefonkostencolumn,             smskostencolumn,             internetkostencolumn,             vertragsdetailscolumn);  }  public static void settable(observablelist datensatz) {     table.setitems(datensatz); } 

so when change static methods/variables non-statics, works fine.

has idea try do? thank you!

your problem static variable not same table view see in ui - fxmlloader can inject instance members, not static members. @ rate, it's not design have ui element static member, because can appear once in application scene graph anyway.

change tableview member non-static member, don't initialize (the fxmlloader inject actual control in ui assuming has proper fx:id attribute). access controller see this question
