javafx 2 - NPE in FXMLLoader -

-

I have a hybrid of Swing (legacy) and Java FX components is one such application. It worked fine until I threw the same as using a preloader place, now all my JavaFX components that fxml files in place and FXMLLoader try do not work because of an NPE New FXMLLoader () (with or without parameters), or FXMLLoader.load () .

I am using 64-bit Java 7u67.

stack shows trace:

On javafx.fxml on javafx.fxml.JavaFXBuilderFactory (JavaFXBuilderFactory.java:85) javafx.fxml.JavaFXBuilderFactory (JavaFXBuilderFactory.java: 53) but java.lang.NullPointerException ... FXMLLoader.load javafx.fxml.FXMLLoader.load on (FXMLLoader.java:2782) (FXMLLoader.java:2771)

His work is square before putting a preloader, a start And after that the main application of the main () method calls it basically the same thing in Preloader, where the main () method of application is called under the preloader () method.

I am stumped as to what is the reason. Any ideas?

I want to review the source code, but the people I found online reported on line # .

Anyway, whatever I saw, being by it, it appears that the default class loader is described in the transition as I have described. Do I have to set class loader for a working example was done to fix the problem, eg, 

  try {fxmlLoader = new FXMLLoader (getClass () getResource ( "Sample .fxml ").). } Grip (Exception e) {FXMLLoader.setDefaultClassLoader (Sample Controller Class. Tags ClassLoader ()); FxmlLoader = New FXML Loader (getClass (). GetResource ("Sample.fxml")); }

Of course, someone can go straight ahead and set the default class loader from the bat.

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
