when calendar timeline set TimeUnit.WEEK and setFirstDayOfWeek=0 then property 'endDate' of null

[hgs1906]

I have some question about using calendar timeline in setting TimeUnit.WEEK and setFirstDayOfWeek=0 (firstDayOfWeek is sunday)
in SmartGWT 12.0p .

I have check some setting , when i set calendarTimeline.setFirstDayOfWeek(0) and
setResolution in TimeUnit.WEEK then it become like this

the week of 2021-03-21 to 2021-03-27 and 2021-04-11 to 2021-04-17 's
CalendarEvent can't be displayed correct (
especially in 2021-04-11 to 2021-04-17 's CalendarEvent), and if i click the gap of CalendarEvent then it throws
Uncaught TypeError: Cannot read property 'endDate' of null


and calendarTimeline.setEndDate(endDate); seems not working .


calendarTimeline.setStartDate(startDate); //03/21
calendarTimeline.setEndDate(endDate); //04/17
CalendarEvent 's startDate and endDate are 03/21 to 03/27 、 03/28 to 04/03 、 04/04 to 04/10 、 04/11 to 04/17


but if i didn't set calendarTimeline.setFirstDayOfWeek(0) it displays correct

thank for you help

Thanks for the report - you didn't mention your build-date and there have been recent enhancements to Calendar/Timeline - so, the first thing to do is retest with the latest patched build of 12.0 from smartclient.com/builds.

If that doesn't address your problem, please show test-code we can run to see the problem (including your Timeline setup and DataSource or test-event).

Also, please confirm your OS/Browser and timezone.

thank's for your replay

i have tested "builds/SmartGWT/12.0p/LGPL/2021-04-20" 、2021-04-26 and latest version of SmartGWT ，
running in opensuse 15.2 、 google chrome 91.0.4472.114 、 Firefox 78.10.0esr 。

they have different display result but still not i want (only dispaly 4 week header and calendarEvent correct display it's width)

where are some test code in Attachments ,
but i can't reproduce the error of "Uncaught TypeError: Cannot read property 'endDate' of null" in that test code ...
so...how can i set calendarline only display 4 header during 4 week and firstDay of week is sunday 。

Thank you for all your assistance。

the power of "Rubber Duck Debugging" !? 囧
after post the replay , i have changed my mind about using

calendar.setResolution(new HeaderLevel[]{new HeaderLevel(TimeUnit.MONTH) , new HeaderLevel(TimeUnit.DAY) } ,TimeUnit.DAY, 28, 7);

instead of

calendar.setResolution(new HeaderLevel[]{new HeaderLevel(TimeUnit.MONTH) , new HeaderLevel(TimeUnit.WEEK) } ,TimeUnit.WEEK, 4, 1);

then..... it run correct and display perfect , only display 4 week header and CalendarEvent's width correct .
whatever in builds 2021-04-20 、2021-04-26 or latest version 。


Hmm …
calendarTimeline.setFirstDayOfWeek(0) and setResolution in TimeUnit.WEEK
seems have some problem that I don’t get .

maybe in TimeUnit.WEEKs Calculation or Offset in FirstDayOfWeek .

thanks for your read and help !!!
