Lightbox error: Cannot read property 'nextSibling' of null

Scheduler Javascript
#1

Hello,

Sometimes when clicking on an event appears a Lightbox with the textbox that has the value of a previously clicked event and this error is showed in the console:

dhtmlxscheduler.js:5457 Uncaught TypeError: Cannot read property ‘nextSibling’ of null
at Object.scheduler._fill_lightbox (dhtmlxscheduler.js:5457)
at Object.scheduler.showLightbox (dhtmlxscheduler.js:5447)
at Object.scheduler._on_dbl_click (dhtmlxscheduler.js:2289)
at HTMLDivElement._obj.ondblclick (dhtmlxscheduler.js:2092)

Thanks.

Hello,

Please create a demo where the problem can be reproduced. You can use DHTMLX snippet system docs.dhtmlx.com/scheduler/snippet/
It is not a known issue, possibly it can be caused by your code.
