Nothing like this happens with just that test code (which is basically the same as the Showcase), and it doesn't make much sense that you could get this bug only on Firefox.

We'd suggest:

1. try compiled mode and if it works, try reinstalling GWT and or your browsers' GWT plugin

2. try a different machine to avoid any issues with Firefox extensions or a corrupt Firefox install

Hi,

I've done all that. And tried to figure it out for last 10h.
I don't get it.
Tried virtual machine with Windows and latest Firefox version. Cleaned for several times all caches and disabled all plugins (for a moment also Firebug).

Here is full standalone test case:

Code:

RestDataSource ds = new RestDataSource();
ds.setDataFormat(DSDataFormat.JSON);
ds.setFetchDataURL("testData/events.json");
		
DataSourceIntegerField idField = new DataSourceIntegerField("id");
idField.setPrimaryKey(true);
ds.addField(idField);

DataSourceTextField nameField = new DataSourceTextField("name");
ds.addField(nameField);
        
DataSourceTextField descField = new DataSourceTextField("description");
ds.addField(descField);

DataSourceDateTimeField startDateField = new DataSourceDateTimeField("date_start");
ds.addField(startDateField);

DataSourceDateTimeField endDateField = new DataSourceDateTimeField("date_end");
ds.addField(endDateField);

Calendar calendar = new Calendar();
calendar.setWidth100();
calendar.setHeight100();
		
calendar.setDataSource(ds);
calendar.setAutoFetchData(true);
		
calendar.setStartDateField("date_start");
calendar.setEndDateField("date_end");
		
calendar.setTimeFormatter(TimeDisplayFormat.TOSHORT24HOURTIME);
		
this.addChild(calendar);

And contents of: testData/events.json

Code:

{  
   "response":{  
      "status":0,
      "startRow":0,
      "endRow":1,
      "totalRows":1,
      "data":[  
         {  
            "id":"2241",
            "date_start":"2015-01-21 19:00:00",
            "date_end":"2015-01-21 22:30:00",
            "name":"aaaa",
            "description":""
         }
      ]
   }
}

The strange thing is this error on developer console:

Code:

02:33:55.535:TMR5:WARN:WeekSchedule:isc_Calendar_0_weekView:getVisibleEvents - event has no start-date: {
    "__ref":"{GWT Java Obj}", 
    "__module":"{GWT Module}", 
    "loadingMarker":true
}

Start date is given. And event is also visible on calendar.
On Chrome this error does not appear

I've attached screenshot from Firebug.

You continue to only show error messages from GWT Development Mode. What happens in compiled mode?

**pH4Lk0n** · 19 Jan 2015, 19:48

I run this in Super Dev Mode not Development Mode and this logs are not copied from GWT Development Mode but SmartClient Developer Console.
GWT Plugin for Firefox was even disabled during last tests.
Effect is the same in Super Dev Mode and after full compilation.

Just tried also GWT Development Mode and errors are the same.

Try also with these options:

Code:

calendar.setShowWorkday(true);
calendar.setWorkdayStart("8:00");
calendar.setWorkdayEnd("18:00");
calendar.setFirstDayOfWeek(1);
calendar.setDisableWeekends(false);
calendar.setTimeFormatter(TimeDisplayFormat.TOSHORT24HOURTIME);
calendar.setScrollToWorkday(true);
calendar.setShowAddEventButton(false);
calendar.setEventOverlap(false);

Hi,

Have you been able to reproduce this problem?
I've checked on two other machines and problem is the same.
And it only affect Firefox.

I've been able to find out that method getVisibleEvents() i CalendarView is called couple hundred of times.
Firstly for empty Record (loadingMarker = true) and then another several times for this one record that was fetched from server.

I've just tried GWT 2.6.1 and situation is the same.
What else can I check??

Best regards

**Isomorphic** · 21 Jan 2015, 01:48

Ok, we've been able to reproduce this with your code - we'll update here when we get to the bottom of it.

**Isomorphic** · 21 Jan 2015, 05:04

We've made changes to address this - please retest with a build dated January 22 or later.

**pH4Lk0n** · 29 Jan 2015, 19:32

Hi,

Sorry for the delay. Didn't get a notification.
I've test latest version (2015-01-29).

It seems like the problem is solved.

Thank you
Best regards

Hi Isomorphic

What is the root cause of these "event has no start-date" messages?
In IE 11 databound Calendar and Timeline show data correct but for each event there is "event has no start-date" warning in development console.

09:45:45.293:TMR0:WARN:TimelineView:isc_ATimeline_0_timelineView:refreshEvents - event has no start-date: {
"__ref":"{GWT Java Obj}",
"__module":"{GWT Module}",
"loadingMarker":true
}

SmartClient Version: v10.0p_2015-05-20/LGPL Development Only (built 2015-05-20)

**Isomorphic** · 20 May 2015, 23:08

Note the "loadingMarker:true" - this would indicate that some code which really should only execute once data has been returned by the server is instead executing while data is still being fetched, when attempts to retrieve Event objects will instead return loading markers like those shown in the logs.

This could be a result of your own code calling APIs before data is loaded, or possibly a framework bug. If you think it might be the latter, try to create a minimal, ready-to-run test case that replicates the problem in an up-to-date build, and we can take a look.

Hi Isomorphic

Thank you for the fast and useful answer. It looks the cause was in pagination I used in DataSource. All warnings disappears as only I have disabled it.
