Matrix and Internet Explorer

I have some problem when i use matrix.js with IE.

Error report:

‘obj.y_unit[…].key’ is null or not an object

The code in matrix .js that it complain about is

scheduler.attachEvent(“onOptionsLoad”,function(){
obj.order = {};
scheduler.callEvent(‘onOptionsLoadStart’, []);
for(var i=0; i<obj.y_unit.length;i++)
obj.order[obj.y_unit[i].key]=i;
scheduler.callEvent(‘onOptionsLoadFinal’, []);
if (scheduler._date && obj.name == scheduler._mode)
scheduler.setCurrentView(scheduler._date, scheduler._mode);
});

Any solution?

Hello,

What scheduler and IE version are you using?
Is the a link where we can check it live?

Kind regards,
