DatePicker::setMaxDate(<date_in_past>) -> calendar view jumps to Jan 0001

Reproducible in: Chrome, Firefox, IE UI5 version: 1.61.1

STR: Select in second datepicker current date: example today is 21 Jan so I select 21 Jan Open first datepicker

Expected: See current month with up to Jan 20 as possible values

Actual: See Jan 0001 as calendar header / values Max date is set to correct value.

Notes: Doesn’t matter if I have a value selected in the first picker or not. Doesn’t matter if I use methods on the datepicker or modify the model and refresh.

<mvc:View controllerName="date-str.date-str.controller.Main" xmlns:html="http://www.w3.org/1999/xhtml" xmlns:mvc="sap.ui.core.mvc"
	displayBlock="true" xmlns="sap.m">
	<App id="idAppControl">
		<pages>
			<Page title="{i18n>title}">
				<content>
					<DatePicker id="start"></DatePicker>
					<DatePicker id="end" change="onChange"></DatePicker>
				</content>
			</Page>
		</pages>
	</App>
</mvc:View>

sap.ui.define([
	"sap/ui/core/mvc/Controller"
], function (Controller) {
	"use strict";

	return Controller.extend("date-str.date-str.controller.Main", {
		onInit: function () {
			var view = this.getView(); 
			this.start = view.byId("start");
			this.end = view.byId("end");
		},
		
		onChange: function(event) {
			var selectedDate = event.getSource().getDateValue();
			var clonedDate = new Date(selectedDate);
			var dateOneDayInPast = new Date(clonedDate.setDate(clonedDate.getDate() - 1));
			this.start.setMaxDate(dateOneDayInPast);
			
		}
	});
});

Hi @krodyrobi,

You could define the initially focused date through the DateTimeField’s initialFocusedDateValue property. After setting the maxDate in your change handler, you could do something like this: this.start.setInitialFocusedDateValue(dateOneDayInPast);

API: https://openui5.hana.ondemand.com/#/api/sap.m.DateTimeField/controlProperties/

Therefore I’m closing the issue.

Thanks & Regards, Diana

When I set the min, max dates to a calendar I’d expect it to grey out dates outside this range, not change the displayed month. The displayed month should either be the current month or a previously viewed month but definitely not the edges of the range in case of one of them is missing.

(-inf, today), (today, +inf) are valid ranges. Why should I be required to fill both, it can default to Jan 0001 but it should not jump to show me that date. I’m not talking about the calendar view but the higher level of abstraction DatePicker.
