HI I have a service which is deployed in my local arcgis server which has world country boundries , when i load just a map it works fine but when i add a query task it hangs , the whole browser system and system hangs can anybody tell what could be the reason , i checked in firebug the query response is in milliseconds still it hangs but there are some other request like http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer/tile/2/0/3 and many more of these which take hell lot of time , please let me know what could the issue.Below is query code
var queryTask = new esri.tasks.QueryTask(url);
var query = new esri.tasks.Query();
query.returnGeometry = true;
query.where = "COUNTRY='India'";
dojo.connect(queryTask, "onComplete", function(featureSet) {
//alert('calling queryTask'+featureSet);
//map.graphics.clear();
try{
/*var sfs = new SimpleFillSymbol(SimpleFillSymbol.STYLE_FORWARD_DIAGONAL, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([255, 0, 0]), 2), new Color([255, 255, 0, 0.5]));
alert('somethign');*/
var symbol = new SimpleFillSymbol(
SimpleFillSymbol.STYLE_SOLID,
new SimpleLineSymbol(
SimpleLineSymbol.STYLE_SOLID,
new Color([255,0,0,0.65]), 2
),
new Color([255,0,0,0.35])
);
//QueryTask returns a featureSet. Loop through features in the featureSet and add them to the map.
dojo.forEach(featureSet.features,function(feature){
alert('feature'+feature);
var graphic = feature;
graphic.setSymbol(symbol);
alert("infoTemplate"+infoTemplate);
graphic.setInfoTemplate(infoTemplate);
alert("graphic"+graphic);
alert("map.graphics"+map.graphics);
map.graphics.add(graphic);
});
}catch(e){
alert("e"+e);
}
});
