B4J Question Layout built with Scenebuilder crashes...

[moster67]

I have this layout built with Scenebuilder and which crashes brutally.

I have ensured that there is nothing in the code-section. I have attached the layout in the sample-app attached. This is the crash:

Waiting for debugger to connect...
Program started.
Error occurred on line: 13 (Main)

Anyone who can explain this and how I can fix it?
Thanks.

For some reason you have an error within the fxml file, you will need to edit the file (use something like notepad++).

Using your example, look in the file scene.fxml where it says fx:controller="app.AppController"

This must refer to a class within your app - I simply changed it to fx:controller="b4j.example.main" and it displayed your screen.

Hope this helps.

That was it!
The layout was imported from an external github-project.

Thank you @Daestrum.
