Renderer and Printtask: Layer grayed out in image

Hi,

Having trouble with printtask and the export web map tool in Javascript API (legacy)

A user selects values from drop downs, then, a function calls a feature service with a unique values based on the field selected.

      ct = new esri.layers.FeatureLayer("http://gis-server.cc.wmich.edu/harcgis/rest/services/hdream/bothcounties_psrazero/MapServer/0",{         mode: esri.layers.FeatureLayer.MODE_ONDEMAND,         opacity: .7,         outFields: ["*"],   //and

     var renderer = new esri.renderer.SimpleRenderer(new esri.symbol.SimpleFillSymbol().setOutline(new esri.symbol.SimpleLineSymbol().setWidth(0.5)));      renderer.setColorInfo({         field: field,           minDataValue: 0,          maxDataValue: maxval,             colors: [               new esri.Color([255, 255, 255]),               new esri.Color([0, 42, 255])             ]           });                                  ct.setRenderer(renderer);             map.addLayer(ct);           map.reorderLayer(ct,4);

Variable maxval is decided by user.

Then the print task:

function print() {      var printUrl = "http://gis-server.cc.wmich.edu/harcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task"; var printTask = new esri.tasks.PrintTask(printUrl);         var params = new esri.tasks.PrintParameters();         var template = new esri.tasks.PrintTemplate();              params.map = map;         template.exportOptions = {             width: 1000,             height: 800,             dpi: 96         };                 template.layout = "MAP_ONLY";         template.preserveScale = false;         template.format = "jpg";         template.showAttribution= "true";           params.template = template;         printTask.execute(params);         dojo.connect(printTask,'onComplete',function(result){   window.open(result.url); }) }

Printing works just fine for other layers, but when the layer ct is added, it appears as a gray box instead of multi -colored choropleth layer.

Is it because the renderer is client-side? How might I get around that so the user can have the choropleth map in the printout?

thanks

To clarify, the JPG image generated shows a gray box, not the actual map window.
