CKEditor at Samples does not work

http://webix.com/demos/material/admin-app/#!/app/product_edit

If you type something then click on any other tab, then click back to MAIN tab, the entry from Full description removed and editor become disabled.

I try to use with own tabbar the same issue, can you help how it can be solved?

one of workaround use tabbar event:

onAfterTabClick : function(){
var editor = $$(“editor”);
editor.setValue( editor.getValue() );
editor._init_ckeditor_once();
}
