I'm gettings these strange crashes in jfxwebkit.dll when I do a JSObject/Node toString. The strange thing is that some JSObject handle toString without problem, these JSObject are referenced from JSObject doc= (JSObject) WebEngine.getDocument(). Nodes that are accessed from a DOM event listener crash and burn when you touch them, except when you reference the Document object.
To reproduce create an empty ViewPart (http://efxclipse.org/tut3.html) and place the following snippets in the public void createPartControl(Composite parent) {} method.
>> Situation 1, content loaded from network..
public void createPartControl(Composite parent) {
FXCanvas canvas= new FXCanvas(parent, SWT.NONE);
WebView view= new WebView();
canvas.setScene(new Scene(view));
final EventListener insert_listener= new EventListener() {
@Override
public void handleEvent(Event event) {
Node inserted_node= (Node) event.getTarget();
// This prints [object HTMLDocument]
System.out.println("inserted_node.getOwnerDocument() - " + inserted_node.getOwnerDocument());
// This crashes the JVM
System.out.println("inserted_node - " + inserted_node);
}
};
view.getEngine().documentProperty().addListener(new ChangeListener<Document>() {
@Override
public void changed(ObservableValue<? extends Document> observable,
Document oldValue, Document newValue) {
if (oldValue instanceof EventTarget)
((EventTarget) oldValue).removeEventListener("DOMNodeInserted", insert_listener, false);
if (newValue instanceof EventTarget)
((EventTarget) newValue).addEventListener("DOMNodeInserted", insert_listener, false);
}
});
view.getEngine().load("http://google.com");
}
>> Situation 2, content loaded from string..
public void createPartControl(Composite parent) {
String html= "<html><head></head><body><h1 id=\"foo\">Hello world</h1></body></html>";
FXCanvas canvas= new FXCanvas(parent, SWT.NONE);
WebView view= new WebView();
canvas.setScene(new Scene(view));
final EventListener click_listener= new EventListener() {
@Override
public void handleEvent(Event event) {
Node clicked_node= (Node) event.getTarget();
// This prints [object HTMLDocument]
System.out.println("clicked_node.getOwnerDocument() - " + clicked_node.getOwnerDocument());
// This crashes the JVM (Click on the <h1> element)
System.out.println("clicked_node - " + clicked_node);
}
};
view.getEngine().documentProperty().addListener(new ChangeListener<Document>() {
@Override
public void changed(ObservableValue<? extends Document> observable,
Document oldValue, Document newValue) {
if (oldValue instanceof EventTarget)
((EventTarget) oldValue).removeEventListener("click", click_listener, false);
if (newValue instanceof EventTarget)
((EventTarget) newValue).addEventListener("click", click_listener, false);
}
});
view.getEngine().loadContent(html);
}
