Caused by: java.lang.NullPointerException
at controllers.Controller.listGCUTours(Controller.java:58)

Check what's happening on line 58, you're calling a method on something that's null.

[ancient totem]

this is line 58 tourListView.setItems(observableList); I dont understand how it wiuld be null...

[junior wharf]

Can you share the full class, and have you placed a breakpoint on that line? Then you can check what's null.

[ancient totem]

putting a breakpoint, it shows tourListView is = null.

here is the code

So that's your issue.

i just have trouble understanding why its null

[junior wharf]

Does it exist in your form?

[ancient totem]

<?import javafx.scene.layout.VBox?>
<?import javafx.scene.control.ListView?>

<VBox xmlns="http://javafx.com/javafx"
      xmlns:fx="http://javafx.com/fxml"
      fx:controller="views.GCUTourListController">

    <ListView fx:id="tourListView" prefWidth="400" prefHeight="300"/>

</VBox>

I believe so
