Please correct the code example

Hi,
The link http://www.mosync.com/documentation/manualpages/how-communicate-between-javascript-and-c-mosync describes Communicating between JavaScript and C++ in MoSync.

In the section (passing parameters to C++) following is written:

If you wish to pass parameters to C++, you add the parameter as a field in the message, for example

bridge.messagehandler.send(  
    { messageName: "Vibrate" 
      duration: "1000" },   
      null); 

When I followed this example, it didn't work. I had to put a comma between the message name and parameter (before the word "duration").

Thanks,

Somnath
