Error Scheduler and Sidebar

Hi webix team,
I put the Scheduler in my Sidebar app and I got an error can’t access property “N”, r is null
look at Code Snippet
Thanks for advice


By default, only the active cell is in the DOM, and the rest do not have any HTML representation at this moment.
This is normal default behavior (saves rendering resources). And with complex widgets it can cause such errors.
To avoid this, you need to use keepViews flag, so that hidden cells also get into the DOM: Code Snippet
