Cannot enable assertions in JavaFX #9194
Description
Apache NetBeans version
Apache NetBeans 28
What happened
When you use Scenebuilder, it creates a skeleton controller class for the scene. The initialize method created by Scenebuilder generates several assert statements validating the state of the GUI variables. This is very useful to ensure the FXML and java class are in synch. The assert statement is default disabled in Java. You must put the -enableassertions option on the Java command.
Unfortunately, when you go to the project properties/Run, the VM options are disabled with the warning, "One of Run/Debug/Profile Project actions has been modified and the Run panel cannot be safely edited."
It would be very useful if assert statements count be enabled somehow.
