Strange error

I’m debugging my application with Firebug. During the load of a complex window it’s produced an error:

this[arr[i].getAttribute( _launchCommands:function(arr){for (va...te("command")].apply(this, args);}},

I’ve tried to run step by step and everything works fine. In normal run they don’t work.

Above error can occur if you are loading xml in grid with some not-exising commands ( head/beforeInit/call or head/afterInit/call )

It possible that command in question is created dynamically or related js script is not loaded on the page yet.
