Can't use Vte.fork_command_full method because of an array problem

[Leonard Messier <leonard messier gmail com>]

Hi there,

I'm struggling to get things working in a very small test application I'm creating. Using the base code I found here :https://developer.gnome.org/gnome-devel-demos/unstable/beginner.js.html.en#tutorials, I created the following :

#!/usr/bin/gjs

// Importing libraries

const GLib   = imports.gi.GLib

    , Gio    = imports.gi.Gio

    , Gtk    = imports.gi.Gtk

    , Lang   = imports.lang

    , Vte    = imports.gi.Vte

;

// Application code

const HelloMe = new Lang.Class({

    // Properties

    Name: "Hello Me"

    // Application initialization

  , _init: function() {

      this.application = new Gtk.Application();

      // Declaring event listeners

      this.application.connect('activate', Lang.bind(this, this.activate));

      this.application.connect('startup', Lang.bind(this, this.startup));

    }

    // Application callbacks

  , activate: function() {

      this._window.present();

    }

  , startup: function() {

      this.render();

    }

  , render: function() {

      var term = new Vte.Terminal()

        , testArray = new Array()

        , anotherTestArray = new Array()

        , pid  

      ;

      anotherTestArray.push('test');

      testArray.push('/bin/bash');

      pid = term.fork_command_full(

          Vte.PtyFlags.DEFAULT

        , '/home/me/' 

        , testArray

        , anotherTestArray

        , null

        , null

        , GLib.SpawnFlags.DO_NOT_REAP_CHILD

        , null

        , null

      );

      term.set_emulation('xterm');

      term.show();

      // Creating application's main window

      this._window = new Gtk.ApplicationWindow({

          application: this.application

        , title:       "Welcome to me"

        , default_height: 200

        , default_width:  400

        , window_position: Gtk.WindowPosition.CENTER

      });

      // Adding the webview to the app and showing

      this._window.add(term);

      this._window.show_all();

    }

});

let app = new HelloMe();

app.application.run(ARGV);

---------------------------------------------

I've been using two things to try and tackle the problem :

The Vte-2.90.gir file on my Ubuntu, located in /usr/lib/gir-1.0 where an automatically generated documentation from the Vte C code source is presented in xml format.

The following site : http://www.roojs.com/seed/gir-1.2-gtk-3.0/gjs/index.html. Where those xml files are presented in a html format, like a regular api.

Nevertheless, I get the following error : 

 gjs embed-term.js

GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.

    JS ERROR: !!!   Exception was: Error: Unhandled array element type 14

    JS ERROR: !!!     lineNumber = '0'

wrapper([object _private_Gtk_Application])@/usr/share/gjs-1.0/lang.js:204

@embed-term.js:77

"'

    JS ERROR: !!!     message = '"this._window is undefined"'

-----------------------------------------------

I gathered that both array I'm using aren't of the expected type. I tried to look into the source code of Gtk itself, but I couldn't go further than locating the problem to the gjs_array_to_array function in the following file https://git.gnome.org/browse/gjs/tree/gi/arg.c?h=gnome-3-8 at line 876, where the element_type is deduced. 

I couldn't find the place where the function g_type_info_get_tag was.

any help would be appreciated !

Thanks in advance
