title: Unity - Photon OnJoinedRoom not being called
body: <p>I am using photon to make a FPS game for android.
  Here is the code:</p>
  
  <pre><code>using UnityEngine;
  using UnityEngine.UI;
  
  public class SceneLoaderButton : Photon.PunBehaviour {
  
  
      public string roomName, mapNameGL, password;
  
  
      public GameObject loadingPan;
  
      public MenuRooms menuManager;
  
      // Use this for initialization
      void Start () {
  
          Button btn = GetComponent&lt;Button&gt; ();
          btn.onClick.AddListener (ConnectCustomRoom);
  
      }
  
      // Update is called once per frame
      void Update () {
  
      }
  
      void ConnectCustomRoom(){
  
          string room = roomName;
  
          RoomInfo[] ri;
          ri = PhotonNetwork.GetRoomList ();
  
          bool correct = false;
  
          string passwd, mapName = "";
          passwd = password;
  
          foreach (RoomInfo info in ri) {
              if (info.name == room) {
                  if (info.customProperties ["Password"].ToString() == passwd) {
                      print(info.playerCount + "/" + info.maxPlayers);
                      if (info.playerCount &lt; info.maxPlayers)
                      {
                          correct = true;
                      }
                      else
                      {
                          menuManager.error("No room for you");
                      }
                      mapName = info.customProperties ["MapName"].ToString ();
                  }
                  else
                  {
                      menuManager.error("Incorrect password");
                  }
              }
          }
          mapNameGL = mapName;
          print(mapNameGL);
  
          if (correct) {
              print("Correct");
              loadingPan.active = !loadingPan.active;
              PhotonNetwork.playerName = "Player" + UnityEngine.Random.Range (1000,9999).ToString();
              PhotonNetwork.JoinRoom(room);
          }
      }
  
  
      void OnJoinedRoom()
      {
          print("Joined room: " + roomName);
          //We joined room, load respective map
          Application.LoadLevel(mapNameGL);
      }
  }
  </code></pre>
  
  <p>This is the code from  button. It is instantiated and it should join the room, then load the scene. In other scripts, "onjoinedroom" callback works, even if I inherite from Photon.MonoBehaveiour, not from PUNBehaveiour. What is wrong?</p>
