Timeline Hours (1 day)

[aciervo]

Hi,
I'am trying GWT Pro 12.1 released February 05, 2021. In production I'm using GWT Pro 12.0.
I have a timeline with Hours (1 day) Resolution but the resolution does not work correctly, the hour starts from 12:00 and not 00:00. In version 12.0 the problem does not exist

How I can fix it?
I include here an example.

Thanks a lot

public class TimelineGroupingSample extends VLayout{
public void build(){
HeaderLevel[] headerLevels = new HeaderLevel[] { new HeaderLevel(TimeUnit.DAY), new HeaderLevel(TimeUnit.HOUR) };

// grouping fields must be specified as laneFields, but can be hidden as is done here
ListGridField groupField = new ListGridField("devGroup");
groupField.setHidden(true);
ListGridField[] laneFields = new ListGridField[]{
new ListGridField("title", "Developer", 120),
groupField
};

Timeline calendar = new Timeline();
calendar.setHeight(551);

calendar.setShowEventDescriptions(false);
calendar.setEventSnapGap(60);
calendar.setLaneEventPadding(2); // add a little space around events
calendar.setStartDate(RelativeDateItem.getAbsoluteDate(RelativeDate.TODAY));
calendar.setCanCreateEvents(true);

// grouping settings
calendar.setCanGroupLanes(true);
calendar.setLaneGroupByField("devGroup");
calendar.setLaneFields(laneFields);

// set up the grid
calendar.setHeaderLevels(headerLevels);
calendar.setResolution(headerLevels, TimeUnit.HOUR, 24, null );

calendar.setLanes(TimelineLaneData.getRecords());
calendar.setData(TimelineData.getRecords());



addMembers(calendar);
}

Instead of using RelativeDateItem.getAbsoluteDate(), which is returning a logicalDate (a date with time set to 12:00), use DateUtil.getStartOf(), ensuring you pass the 3rd parameter, which will return the start of the, in your case, day, in your timezone.

Edit: we added a follow-up post to this but removed it - the alternate value we suggested, START_OF_TODAY, is documented as being identical to RelativeDate.TODAY.

We're taking a look at whether there's a bug here.

I used DateUtil.getStartOf and even without setting the date the problem is exactly the same.

Also, in your showcase: https://www.smartclient.com/smartgwt...ine_resolution, in Hours (1), after choosing a new Date from DateChooser button the hour starts from 12:00.

In addition I would like only one day (ex: Feb, 11) not the range (Feb, 11-12)

Thanks a lot.

Ok, so the DateChooser is producing a logicalDate - we'll take a look and update here shortly.

Hi, we would like use GWT Pro 12.1 but there is the same error that I have described to you above

Can you fix it?
Thanks a lot

Changes were made a while ago to address the 12 noon issue - we just tested this at the link you provided, which is running a build from May 1, and we see no issues with dates or times.

We do see the title label above the timeline showing a range (from date to date+1) - this is just because the end time is midnight, and we'll address the default text.

Note that you can override Timeline.getDateLabelText() to provide custom text.
