Hi Team,

I am facing an error if grid has filterbar and first column is data column(means I havn't added checkbox column at first place). So once grid loaded and user click on first column sorting and then hit tab. Suddenly a error message comming from Library onTab method.

Note: this is only happening only once. To reproduce it you need to refresh your page again.
