Stub example incorrect

[janwinkler]

The stub example is incorrect (the function __gpp_stub still returns the values instead of calling the callback).

Corrected function:

window.__gpp_stub       = function ()
  {
   var b       = arguments;
   __gpp.queue = __gpp.queue || [];
   if (!b.length)
   { return __gpp.queue; }
   var cmd = b[0];
   var clb = b.length > 1 ? b[1] : null;
   var par = b.length > 2 ? b[2] : null;
   var result = null;
   if (cmd === 'ping')
   {
    result = {
     gppVersion:         '1.1', // must be “Version.Subversion”, current: “1.1”
     cmpStatus:          'stub', // possible values: stub, loading, loaded, error
     cmpDisplayStatus:   'hidden', // possible values: hidden, visible, disabled
     supportedAPIs:      ['2:tcfeuv2', '5:tcfcav1', '6:uspv1'], // list of supported APIs
     signalStatus : 'not ready',
     cmpId:              31, // IAB assigned CMP ID, may be 0 during stub/loading
     sectionList:        [],
     applicableSections: [-1], //or 0 or ID set by publisher
     gppString:          ''
    };
   }
   else if (cmd === 'addEventListener')
   {
    __gpp.events = __gpp.events || [];
    if (!('lastId' in __gpp))
    { __gpp.lastId = 0; }
    __gpp.lastId++;
    var lnr = __gpp.lastId;
    __gpp.events.push({
                       'id':        lnr,
                       'callback':  clb,
                       'parameter': par
                      });
    result = {
     eventName:  'listenerRegistered',
     listenerId: lnr, // Registered ID of the listener
     data:       true, // positive signal
     pingData:   {
      gppVersion:         '1.1',

      cmpDisplayStatus:   'hidden',
      supportedAPIs:      ['2:tcfeuv2', '5:tcfcav1', '9:usva', '7:usnat'],
      cmpId:              31,
      sectionList:        [],
      applicableSections: [-1], //or 0 or ID set by publisher
      gppString:          ''
     }
    };
   }
   else if (cmd === 'removeEventListener')
   {
    var success  = false;
    __gpp.events = __gpp.events || [];
    for (var i = 0; i < __gpp.events.length; i++)
    {
     if (__gpp.events[i].id == par)
     {
      __gpp.events[i].splice(i, 1);
      success = true;
      break;
     }
    }
    result = {
     eventName:  'listenerRemoved',
     listenerId: par, // Registered ID of the listener
     data:       success, // status info
     pingData:   {
      gppVersion:         '1.1',

      gppString:          ''

    };
   }
   //queue all other commands
   else
   {
    __gpp.queue.push([].slice.apply(b));
