[/java]
happens when i put the
[xml]
<screen … controller = "controllers/EditingGUI" />
[/xml]
I believe it should run with the implements ScreenController, Controller. Double checked if it was the controller misspelled or inverted slashes in path but no… Could i please get info on what happened here and how to do this?
thanks
Next lies my codes
the line 102 of EditingGUI was in here
[java]
public void share(AssetManager am, InputManager im, AudioRenderer ar, ViewPort guiViewPort ) {
assetManager = am;
niftyDisplay = new NiftyJmeDisplay(am,im,ar,guiViewPort);
editNifty = niftyDisplay.getNifty();
editNifty.loadStyleFile("nifty-default-styles.xml");
editNifty.loadControlFile("nifty-default-controls.xml");
guiViewPort.addProcessor(niftyDisplay);
// editNifty.addXml("Interface/Debug.xml");
// editNifty.fromXmlWithoutStartScreen("Interface/Debug.xml");
editNifty.fromXml("Interface/Debug.xml", "main"); // <<here
npcs = new Node("NPCs");
objs = new Node("Objects");
prts = new Node("Particles");

What package is your controller in?
in controllers package… The testEdit as well in its correct package. I used the refactor wizard several times lately.
You should use a correct package name. That was the first thing that struck me as odd though so if you are specifying the controller class correctly I don’t know what the problem is.
Do you have a no-arguments constructor on the controller? Have you tried instantiating the controller yourself and passing it to fromXml?
abt the no-arguments constructor, I think that would be a popup builder present there.
@zarch good heavens Gracias! Just did the instantiating. I got it running. But i wonder… did the code really changed? Anyway it’s working. Thanks much!

changed line after and done… 
The package name in for
[java]
<screen … controller = "controllers/EditingGUI" />
[/java]
should be a java package name, eg:
[java]
<screen … controller = "controllers.EditingGUI" />
[/java]
I think so anyway…
