You may be running into the issue described in the following forum thread. This is a problem only in IE, here's the bug number and the link below has a patch you can apply: NIM054763: When running an application that uses the Dojo Border Container and Content Panes for layout an invalid argument error occurs when the browser is resized. This only happens in IE. http://forums.esri.com/Thread.asp?c=158&f=2396&t=301691&mc=5

Ravi, We don't have a method directly on the feature layer to apply a spatial filter - I don't see one in Flex either. However if you want to apply a spatial query directly to the feature layer one approach would be to add a feature layer in selection mode then use selectFeatures to perform a spatial query. Here's a sample that shows how this works, here only features within the specified extent are drawn on the map. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

I think it might be the symbology, can you try replacing the line where the renderer for the selection layer with this one: selectionLayer.setRenderer(new esri.renderer.SimpleRenderer(new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_DASH,new dojo.Color([0,255,200]), 14))); And the default renderer line with this one: var defaultRenderer = new esri.renderer.SimpleRenderer(new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255,0,0]), 2));

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.

Ravi, You can use the queryFeatures method to query the feature layer using a spatial filter. The queryFeatures method takes in input query that has a geometry property you can use to define the filter geometry. http://help.arcgis.com/EN/webapi/javascript/arcgis/help/jsapi_start.htm#jsapi/query.htm

If you add a breakpoint, using a tool like Firebug for Firefox or Developer Tools in IE is there a value returned for the OBJECTID associated with the graphic. The snippet of code below is executed when you hover over a row in the data grid. Dojo.some looks through all the map's graphics until it finds one that meets the criteria. In this case once a graphic is found with the same objectid as the row's id then it will add a selection graphic to the map.
dojo.some(map.graphics.graphics,function(graphic){
if ((graphic.attributes) && graphic.attributes.OBJECTID === rowId) {
var selectedState = new esri.Graphic(graphic.geometry).setAttributes(
graphic.attributes);
selectionLayer.add(selectedState);
return true;
}
});

You mentioned that the selection isn't syncing up - does this mean that features are getting selected but maybe not the ones you'd expect?

I setup a quick test using the code below and cannot reproduce the problem. In this test case if you run the application then move both sliders to the same position and start playing you'll see that data displays on the map. It looks like you have an extra space in the following line, perhaps this is the issue or maybe it was an error when copying the code? timeSlider.createTimeStopsByTimeInterval(timeExten t, 1, 'esriTimeUnitsDays'); Here's my test case: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

Based on your screen shot the portion of the slider that you are trying to overwrite is the dijitSliderDecrementIconV not the IconH. I ran a quick test and can reproduce the issue in IE6 but I was able to overwrite the css using something like this. If you post the css you are using to workaround this issue I'd be happy to take a look .nihilo .dijitSliderDecrementIconV {
background:url("images/minus.png") no-repeat scroll 2px transparent ;
cursor:pointer;
height:18px;
width:18px;
}

This text is displayed in the direction info - you could associate a location name rather than address if you wish, for example if I wanted driving directions to display ESRI Redlands and San Diego convention center instead of an address I could add an address attribute with the following information:
var fromLoc = new esri.geometry.Point( -117.194958859564,34.0573637535114,map.spatialReference);
routeParams.stops.features[0] = map.graphics.add(new esri.Graphic(fromLoc, fromSymbol,{address:"ESRI Redlands"}));
var toLoc = new esri.geometry.Point(-117.163797351249,32.7075263536336,map.spatialReference); routeParams.stops.features[1] = map.graphics.add(new esri.Graphic(toLoc, toSymbol,{address:"San Diego Convention Center"}));

Bob, I haven't run into this issue, perhaps there's something missing in the code? Can you post the portion of your code that sets up the editor? Thanks Kelly

Your code was close - but you have to wait until the map loads to add graphics. In the snippet below note that it waits until the onLoad event fires to add the graphics to the map. function init() {
var startExtent = new esri.geometry.Extent(-102.5,36.8,-99.8,38.4, new esri.SpatialReference({wkid:4326}) );
var map = new esri.Map("map", {extent:startExtent});
var tiledMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer");
map.addLayer(tiledMapServiceLayer);
dojo.connect(map, 'onLoad', function(map) {
//Create graphics layer for counties
var countyLayer = new esri.layers.GraphicsLayer();
var lat=null
var lon=null;
var markerSymbol = new esri.symbol.SimpleMarkerSymbol();
var atts = {};
atts["ID"] = 1;
lat=37.514;
lon=-101.1719;
var location = new esri.geometry.Point(lon, lat, new esri.SpatialReference({wkid:4326}));
var graphic = new esri.Graphic(location, markerSymbol, atts);
graphic.titleField = "ID";
countyLayer.add(graphic);
map.addLayer(countyLayer);
});
}

Sure this is possible. If you look at the 'Get Driving Directions' sample you'll see that the input address is geocoded and the x,y values of the best match are used to create a new graphic which is are used as the inputs to the route task. if (type === "from") {
routeParams.stops.features[0] = map.graphics.add(new esri.Graphic(stop.location, fromSymbol, { address:stop.address, score:stop.score }));
}
else if (type === "to") {
routeParams.stops.features[1] = map.graphics.add(new esri.Graphic(stop.location, toSymbol, { address:stop.address, score:stop.score }));
} In the above code you can replace stop.location with a new point that contains the lat,lon values instead.
