Dear,Thanks. But would it be possilbe to explain me what the code you inserted does? I do not fully understand.In my code I tried to call the layer via:protected function widgetOpenedHandler(event:Event):void
{
map.timeSlider = myTimeSlider;
fLayer= map.getLayer(idlayer);
fLayer.mode = "snapshot";
var timeInfo:TimeInfo=fLayer.layerDetails.timeInfo;
var timeInterval:int=timeInt.value;
myTimeSlider.createTimeStopsByTimeInterval(timeInfo.timeExtent,timeInterval,timeInfo.timeIntervalUnits);
}I understand now that layer does not have the attribute 'id'. I thought it did because of the syntax mentioned in http://help.arcgis.com/en/webapi/flex/apiref/index.html. It is mentioned:getLayer () method public function getLayer(layerId:String):LayerReturns an individual layer of a map. Parameters layerId:String �?? The layer identifier. Returns Layer �?? The layer associated with ID. If not found, null is returned. -> but i understand now that it only existis for sublayers. However, can you help me with the code you wrote?1) so it cannot work with "getlayer"?2) the code is not working (I only renamed myLayer by fLayer not having to change it everywhere in my mxml. But I get the error on the line "var layer:Layer = null;" error: Type was not found or was not a compile type constant: Layer.My code:In the config.xml:<operationallayers>
<layer label="Test" type="feature" url="http://trainingcloud.arcgis.com/ArcGIS/rest/services/Redlands_Collisions2008/MapServer/0"/>

As you can read in documentation (Flex Viewer version 2.5) about config.xml layer tag (if you can read), <layer> has no id attribute.
So what documentation you read? Can you provide me with link.
