How to loop sound effect?

How to loop sound effect?
0.0 0


In the documentation on this page: is method:

playEffect(path, loop)
Play sound effect.

var soundId = cc.AudioEngine.getInstance().playEffect(path);

{String} path
   The path of the sound effect with filename extension.
{Boolean} loop
   Whether to loop the effect playing, default value is false

But when I try to loop effect I have following error:
jsb: ERROR in JSB_SimpleAudioEngine_playEffect_pitch_pan_gain_: Error in number of arguments

Is documentation wrong or there is a bug?
