Time extent data not displayed for single day

Question

Hi,

I am working on application which requires TimeExtent feature. I created a timeextent and a timeslider and for the timeslider i created timestops as type esritimeunitsdays. The problem is when the right and left thumb of the timeslider are same i.e. records of a single day the map doesn't show the features on the map. This is because my startTime and endTime are same so the map is not getting the data for the day. Is there any workaround for this issue.

I am adding the code of the same:

var timeExtent = new esri.TimeExtent();
    var todayDate = new Date();
    timeExtent.startTime = new Date((todayDate.getMonth() + 2) + "/" + 1 + "/" + (todayDate.getFullYear() - 1) + " UTC");
    timeExtent.endTime = new Date((todayDate.getMonth() + 1) + "/" + GetLastDay() + "/" + todayDate.getFullYear() + " UTC");
    featureLayer.setTimeDefinition(timeExtent);

var timeSlider = new esri.dijit.TimeSlider({}, dojo.byId("monthslider"));
    map.setTimeSlider(timeSlider);
    timeSlider.setThumbCount(2);
    timeSlider.createTimeStopsByTimeInterval(timeExtent, 1, 'esriTimeUnitsDays');
    timeSlider.setThumbIndexes([300, 365]);
    timeSlider.startup();

Regards,
Ravi.

I'm experiencing this same problem.  When I have a two thumb slider, and both are sitting on the same year, no data appears on my map.  Has this issue been resolved?

Kelly,

It works fine if I use a featurelayer with my mapservice. however, it doesnt work when I instantiate a featurelayer from the same featureservice. I need to perform edits on this layer and hence have to use featureservice.

Another point I have noticed in all jsapi samples is that featurelayers are created from a mapservice (except for editing samples). Is this due to any limitation of any kind or just a recommended practice?

Ravi,

I switched my test case to use a feature layer instead, mine is a feature layer pointing to a map service and the test case still works. This service is public if you'd like to test:opLayer = new esri.layers.FeatureLayer("http://servicesbeta.esri.com/ArcGIS/rest/services/Health/h1n1/MapServer/0",{
          mode: esri.layers.FeatureLayer.MODE_SNAPSHOT
});

Which mode are you specifying for your feature layer? We recommend using MODE_SNAPSHOT if you aren't using a large amount of data. If you have a large amount of data you may want to use an ArcGISDynamicMapServiceLayer instead.  ONDEMAND_MODE is not recommended because it can result in too many requests to the server.
