Bug: Calendar does not redraw events when style changes

[atomatom]

Using last nights nightly build; I think this is a new bug as this was working a few weeks ago.

When a Databound calendar event comes back from the server with a new value for eventWindowStyle the Calendar widget does not redraw it with the correct style. If I refresh the window or force an invalidateCache then the new style is drawn.

The simplest reproduction is to modify the databound calendar example and return a different
eventWindowStyle

Not clear this is a new bug, two week old version had same issue.

hi, atomatom
I could add events for a single day in the calendar widget. Now I want to add an event starting from today 11:00 pm and extending the same event to tomorrow 10:00 am. How can I add an event like this? Help me plz...........

A few quick tests aren't showing this behavior for us - can you provide browser details and code that fails or more specific steps to reproduce?

angelrani: we don't currently support multi-day events

Hi, isomorphic
Thanks for your information. I want to customize 12 hour based calendar in which i can set the start day of the week using calendar.setFirstDayOfWeek(1); but i can't change the default time settings (12.00am to 11.00pm) in the left side of the calendar..(for example, i want to set the time starting from 6.00am to 5.00pm).Also same case with 24 hr based calendar.Can anybody help me please...it's very urgent.....

Yesterday, I saw this on XP/Firefox 3.6. I'm seeing it now on Ubuntu 10.04/Firefox 3.6. I just tried it in Chrome, same thing. Same effect compiled and hosted mode

Here's a test case, (using the CalendarData sample data from the showcase).

Move events around, they don't change colour/style.

Interestingly, if you delete an event (hit the top right X on the event), then the events are redrawn and the style applied.

		Calendar calendar = new Calendar();
		addMember(calendar);
		setWidth100();
		setHeight100();

		calendar.setData(CalendarData.getNewRecords());

		calendar.addEventMovedHandler(new EventMovedHandler() {
			private String eventWindowStyle = null;
			private boolean flip;
			private String style1 = "green";
			private String style2 = "pink";

			@Override
			public void onEventMoved(CalendarEventMoved event) {
				CalendarEvent calendarEvent = event.getEvent();
				if (flip = !flip) {
					eventWindowStyle = style1;
				} else
					eventWindowStyle = style2;
				calendarEvent.setEventWindowStyle(eventWindowStyle);
				calendarEvent.setDescription(eventWindowStyle);
			}
		});

You could try something funky with timezones and using

	calendar.setDateFormatter(dateFormatter)

I had multi-events working by chopping events up into day slices. Not a pretty solution. I'm not using it like that anymore. You might want to check out other GWT calendar solutions like http://code.google.com/p/gwt-cal/ - unfortunately it has a shitty licence or is expensive for a single component (but then again, hopefully you're paying for the developer to eat and put energy into the project)

ps, don't jack threads with unrelated questions - start a new one. :)

Timezones won't help, sorry for wild-guess suggestion.

Styling is automatically updated if you are working with a DataSource and use updateData().

[atomatom]

My real case is using a DataSource. I am not explicitly calling updateData though; doesn't the Calendar use that by default on a drag operation? The thing that seems fishy to me is that the description/title/etc all update but the style does not.

I have a hack to fix the current behavior; add an event then delete it. (I think that should work)

[atomatom]

Is this a WONT_FIX or will this be fixed? My test case should work, no?

Styling is automatically updated if you are working with a DataSource and use updateData().

I use a RestDataSource and updateData() and had to force reload data, because in 3.1 LGPL styling isn't updated (checked on FF 16.0.1, Chrome 26.0.1410.43, IE 10.0.9200.16521 - Win7).

In this case also CanEditField doesn't work.
(I use updateData() to lock event - so locked event has different style and shouldn't be editable)


If I use custom form to edit events and then call form.saveData() - this updates styling and canEdit feature !


p.s.
and, by the way, it would be nice if
Calendar.updateData() had DSCallback parameter

[Isomorphic]

This suggests the return data from your RestDataSource is incorrect in the case where you directly call updateData() - see the FAQ on grids not automatically updating.
