Why does this popup still

Hello,

The required attribute is defined in BaseOrderPageV2 of Order package.

It is necessary to create the replacing view model with Base Order page and following code

 define("BaseOrderPage", [], function() {
	return {
		entitySchemaName: "Order",
		attributes: {
				"Client": {
					"caption": {"bindTo": "Resources.Strings.Client"},
					"dataValueType": this.Terrasoft.DataValueType.LOOKUP,
					"multiLookupColumns": ["Contact", "Account"],
					"isRequired": false
				},
			},
		modules: /**SCHEMA_MODULES*/{}/**SCHEMA_MODULES*/,
		details: /**SCHEMA_DETAILS*/{}/**SCHEMA_DETAILS*/,
		businessRules: /**SCHEMA_BUSINESS_RULES*/{}/**SCHEMA_BUSINESS_RULES*/,
		methods: {
			validateAccountOrContactFilling: function(callback, scope){
				var result = {
						success: true
					};
				callback.call(scope || this, result);
			}
		},
		dataModels: /**SCHEMA_DATA_MODELS*/{}/**SCHEMA_DATA_MODELS*/,
		diff: /**SCHEMA_DIFF*/[]/**SCHEMA_DIFF*/
	};
});

and the result:
