Methods of second class on DBus not callable - dbus

Question

I created Dbus service with Vala language. It creates interface to add devices with different paths. Device must scan dir and bind methods on subpath.
Then i call su.example.Phone.AddBySyspath(/sys/bus/usb/devices/2-2.4), it returns "/su/example/phone/2_2d4" as expected. But calling Reset on this path causes "Unable to find method Reset on path /su/example/phone/2_2d4 in interface su.example.Phone".
I have code:
using Gee;
[DBus (name = "su.example.Phone")]
public class Phone : Object {
Regex ttyregex;
string path;
string manufacturer;
public Phone(string path){
this.path = path;
this.ttyregex = new Regex ("tty[A-Z0-9]+");
this.manufacturer = "Unknown";
load();
}
private async void load(){
string[3] ttys = {"", "", ""};
var dir = File.new_for_path (path);
stderr.printf ("path %s\n", path);
FindTTY(dir,0,ttys);
stdout.printf ("done\n");
}
private void FindTTY(File dir, int sub, string[] ttys){
sub++;
FileEnumerator enumerator = dir.enumerate_children(
"standard::*",
FileQueryInfoFlags.NONE
);
FileInfo info = null;
while
((info = enumerator.next_file ()) != null)
{
var name = info.get_name ();
if (name == "manufacturer") {
File f = dir.resolve_relative_path (info.get_name ());
var dis = new DataInputStream (f.read ());
manufacturer = dis.read_line (null);
}
stdout.printf ("%s\n", info.get_name ());
stdout.printf ("%d\n", info.get_file_type ());
}
}
public string reset() throws Error {
stdout.printf ("ATZ\n");
return "OK";
}
}
[DBus (name = "su.example.Phone")]
public class PhoneServer : Object {
Regex dotregex;
Regex nonalpharegex;
private DBusConnection conn;
private HashMap<string, Phone> map;
public PhoneServer(DBusConnection conn) {
this.conn = conn;
this.map = new HashMap<string, Phone> ();
this.dotregex = new Regex ("[.]+");
this.nonalpharegex = new Regex ("\\W+");
}
public string add_by_syspath(string path, GLib.BusName sender) throws Error {
// path = /sys/bus/usb/devices/2-2.4
var pathv = path.split("/");
string name = pathv[pathv.length-1];
name = dotregex.replace(name,name.length,0, "d");
name = nonalpharegex.replace(name,name.length,0, "_");
stderr.printf ("name %s\n", name);
var buspath = "/su/example/phone/%s".printf(name);
if (map.has_key(name)) {
} else {
var phone = new Phone (path);
map.set(name,phone);
try {
conn.register_object ("/su/example/phone/%s".printf(name), phone);
} catch (IOError e) {
stderr.printf ("Could not register service\n");
}
}
return buspath;
}
}
[DBus (name = "su.example.PhoneError")]
public errordomain PhoneError
{
SOME_ERROR
}
void on_bus_aquired (DBusConnection conn) {
try {
conn.register_object ("/su/example/phone", new PhoneServer (conn));
} catch (IOError e) {
stderr.printf ("Could not register service\n");
}
}
void main (string[] args) {
Bus.own_name (BusType.SYSTEM, "su.example.Phone", BusNameOwnerFlags.NONE,
on_bus_aquired,
() => {},
() => stderr.printf ("Could not aquire name\n"));
new MainLoop ().run ();
}

Answer 1

While writing question i solved this.
I need to use different DBus names for handler classes:
[DBus (name = "su.eerie.PhoneManager.Phone")]
public class Phone : Object {
...
[DBus (name = "su.eerie.PhoneManager")]
public class PhoneServer : Object {
...
