how to init/define pattern in protoUI

Webix JS
#1 

webix.protoUI({
  name:"isodate",
  $cssName: 'datepicker',
  defaults:{
    type:"text",
    icon:"calendar",
    placeholder:"yyyy-mm-dd",
    pattern:{ mask:"####-##-##", allow:/[0-9]/g} 
}, webix.ui.text);

pattern is attached to webix.ui.text through webix.extend, but i don’t know how to make use of it.

#2

Is below solution acceptable?
Can it be merged in next webix version?

this is around line 34477 in webix_debug.js in Webix 5.4


	webix.extend(webix.ui.text, {
		$init:function(config){
//		  if(config.pattern || (config.format && !this.format_setter)){
		  if(this.defaults.pattern || config.pattern ||  (config.format && !this.format_setter)){

and line 26727 in Webix 6.0.3


var TextPattern = {
	  $init: function $init(config) {
	    if (this.defaults.pattern || config.pattern || config.format && !this.format_setter) {

Hello,

We will consider adding such an improvement in the pattern code, thanks for suggesting.

The functionality was improved in 6.0.6 Code Snippet.
