[SOLVED] Problem with readSavableArrayList

Troubleshooting
1

Is that functionality working ? Or Am doing something wrong (never used salvable before :P) ?
The data was saved using the writeSavableArrayList ok, the file is in the diretory with data, but the load gets this error :

java.lang.InstantiationException: mygame.ProfileLoader$Profile
	at java.lang.Class.newInstance(Class.java:359)

I already tried to remove the file and re-create, same results.
Any tip on what should be the cause ?

Some code :

public class ProfileLoader implements Savable {
...
	public class Profile implements Cloneable,Savable {
		String name = "";
		...
         	public void write(JmeExporter ex) throws IOException {
         		OutputCapsule capsule = ex.getCapsule(this); 
         		capsule.write(name,"name", "Default");
			...
		}
		public void read(JmeImporter im) throws IOException {
            		InputCapsule capsule = im.getCapsule(this);
            		name                = capsule.readString("name", "Default");
			...
		}
	}
	public ArrayList<ProfileLoader.Profile> profileList = new ArrayList<ProfileLoader.Profile>();
	...
	public void saveData() {
        	try { SaveGame.saveGame("profiles", "profiles", Main.profile); } catch (Exception except) {
            	System.out.println(except.toString());
            	except.printStackTrace();
        	}
    	};

	public void loadData() {
		Main.profile=null;
		try { Main.profile = (ProfileLoader) SaveGame.loadGame("profiles", "profiles"); } catch (Exception except) {
			System.out.println(except.toString());
			except.printStackTrace();
		}
		if(Main.profile==null) Main.profile = new ProfileLoader();
	}
	public void write(JmeExporter ex) throws IOException {
		OutputCapsule capsule = ex.getCapsule(this); //http://wiki.jmonkeyengine.org/doku.php/jme3:advanced:save_and_load
		capsule.writeSavableArrayList(profileList, "profilelist", new ArrayList<ProfileLoader.Profile>());
	}

	public void read(JmeImporter im) throws IOException {
		InputCapsule capsule = im.getCapsule(this);
		profileList  = capsule.readSavableArrayList("profilelist",  new ArrayList<ProfileLoader.Profile>());
	}
}

Your Profile class doesn’t have a no-arg constructor and so can’t be instantiated.

The log says about the Profile constructor, but it has constructor :

public Profile() {}

SEVERE: Could not access constructor of class ‘mygame.ProfileLoader$Profile’!
Some types need to have the BinaryImporter set up in a special way. Please doublecheck the setup.
Aug 08, 2015 7:27:22 PM class com.jme3.export.binary.BinaryImporter readObject(int id)
SEVERE: Exception
java.lang.InstantiationException: mygame.ProfileLoader$Profile

the inner class needs to be static if you want it to be instanciable through reflection.

 public static class Profile ...

Yes you was right ! Its working now !
Millions of thank you !
