http://docs.webix.com/api__refs__common_helpers.html lists “delay” apparently twice. The second one is webix.ui.delay and perhaps should appear as “ui.delay” in the Methods list. Or “ui” methods should be under a separate heading.
Also, at http://docs.webix.com/api__ui_delay.html,
The difference is that ui creates the view immeadiately, while webix.delay initializes the view
Should have “webix.ui.delay” there.
