I create a layer and upload to my arcgisserver, it displays well. I can see and click the symbol when i make a query.
However, when i add the base map, the symbols of query's results could not display or click.
map = new esri.Map("mapDiv", {

          basemap: "hybrid",// have a base map. Remove this code to delete the base map.

          center: [-34.541, 32.843],
          zoom: 3

When i try to use a layer from:
Everything works fine.

I really don't know how to fix it. Here is information of my layer.

Drawing Info: 
Simple Renderer: 
Simple Fill Symbol:
Style: esriSFSSolid, Color: [Undefined]
Simple Line Symbol:
Style: esriSLSSolid, Color: [255, 255, 255, 255], Width: 1

Here is information of the sample:
Drawing Info: 
Simple Renderer: 
Simple Fill Symbol:
Style: esriSFSSolid, Color: [206, 205, 250, 255]
Simple Line Symbol:
Style: esriSLSSolid, Color: [110, 110, 110, 255], Width: 0.4
