kanban custom editor

Webix JS
#1

how can I use the same options in CustomEditor when selecting users via a richselect?

If I specify the options as Url as shown below, this will work, but two GET requests (usersUrl) will be triggered.
This does not seem to be the case when using the DefaultEditor.

webix.ui({
	view:"kanban",
	editor:[
	  { view:"textarea", name:"text", label:"text", height: 90},
	  { view:"richselect", name:"user_id", label:"user_id", options: usersUrl}
	],
	comments:{ 
		currentUser: currentUserID 
	},
	cols:[
		{ header:"Backlog", body:{ view:"kanbanlist", status:"new" }},
		{ header:"In Progress", body:{ view:"kanbanlist", status:"work" }},
		{ header:"Testing", body:{ view:"kanbanlist", status:"test" }},
		{ header:"Done", body:{ view:"kanbanlist", status:"done" }}
	],
	url: dataUrl,
	save: dataUrl,
	attachments: attUrl,
	users: usersUrl
});

Hello,

You can use

var store = new webix.DataCollection({ url:usersUrl })

and add it to the options of the editor as options: store;
