【问题描述】：
谢谢大家，问题与文件加载无关，而是与代码的不同部分有关。很抱歉浪费您的时间，但还是谢谢您！

我以前在这里看到过这个问题，但每当我尝试解决我的问题时，它都不起作用。
当尝试在 java fxml 中加载新窗口时，我使用这种方法：
public void openContacts(ActionEvent event) {
try {
Parent root = FXMLLoader.load(getClass().getResource("/application/CV.fxml"));
Scene scene = new Scene(root);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
Stage stage = new Stage();
stage.setScene(scene);
stage.show();
}
catch(Exception e) {
System.out.println(e);
}
}
但我得到了这个例外：
javafx.fxml.LoadException:
/C:/Users/tomer/eclipse-workspace/PhoneProj%20V3/bin/application/CV.fxml
有什么帮助吗？谢谢！
编辑：完整的错误信息

有人建议更改项目名称并删除空间，没有做任何事情...... 我还尝试给出文件的完整路径名，而不仅仅是“/application/CV.fxml”。 （全路径名为“C:\Users\tomer\eclipse-workspace\PhoneProjV3\src\application\CV.fxml”）
【问题讨论】：
-
请edit您的问题包含完整 stack trace。
-
编辑的时候还要贴出文件夹结构。
-
一些产生
null的表达式在 MainController.java 第 51 行被取消引用 -
请注意，
LoadException可能不是真正的问题。有Caused bys吗？ -
@Slaw 我得到了一个由 ComboBox 负载引起的（即使它填满就好了）
