John Brice updated NETBEANS-1785:
---------------------------------
Description:
Pasting code into JavaFX start method of a Java application, NetBeans offers to
resolve imports. Clicking OK results in a Null Pointer Exception. Cancel the
dialog, then Ctrl+Shift+I imports correct classes.
Steps to reproduce:
Create new Java application.
Add OpenJFX jars to classpath and modulepath.
Add --module-path %PATH_TO_FX% and --add-modules javafx.controls,javafx.fxml
to VM options.
Make main class extend Application, implement all abstract methods, change
main method body to:
{code:java}
public static void main(String[] args) {
launch(args);
}{code}
Paste this code into start method:
{code:java}
@Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("FTGui.fxml"));
stage.setTitle("Hello World");
stage.setScene(new Scene(root, 300, 275));
stage.show();
}{code}
Netbeans dialog pops up offering to resolve imports for pasted code.
Click OK, get NPE.
