B4J Question FXML load exception when loading file designed through scene builder

[VB6Back]

Hello All,

I am relatively new to the Java world and totally new to B4J. I am glad this product exists comming from a VB6 background.

I designed a test form using scene builder. I have attached the fxml file. When I try to load it through B4J AppStart I get the following error:

Error occurred on line: 13 (main).
javafx.fxml.LoadException: Invalid property.

I am able to preview the form through scene builder without a problem.

I appreciate any help on this.

I tested it with Java 8 and it works:

Hi Erel,

Thank you so much for your prompt reply. I installed JDK8 and worked like a charm. I am not sure why it didn't work under JDK7 but I guess I need to do a lot of reading to find out...

Hello,
I got the same problem with jdk 1.7, which could be solved by upgrading to jdk 1.8
Thanks for the hint !
