'undefined' is null or not an object

Scheduler Javascript
#1

This error appears only when using IE and the page does not render.
When debugging, it shows that the issue is in dhtmlxscheduler_treetimeline.js line 11 char 102.
Other browsers do not have an issue. How can this be corrected in IE? Thanks

Hello,

So is it not working in IE at all or only sometimes? If sometimes - when under what conditions, how can we reproduce it?
What IE version?

Kind regards,
Ilya

found the issue. Had extra commas in the nested array. looks like IE has a hard time handling those issues. thanks
