Print Dijit Template Question

[Anonymous User]

Attempting to specify which layers are to be included in the legend using the Print Dijit Template sample. However the following line of code essentially bombs the app.

var legendLayer = new esri.tasks.LegendLayer();

Any ideas?

Thanks!

try setting a layerId (and optionally subLayerIds) for legendLayers before the object is passed in the layoutOptions

http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/printtemplate.htm#layoutOptions

var myLegendLayer = new esri.tasks.LegendLayer();
myLegendLayer.layerId = "Boundaries";
myLegendLayer.subLayerIds = [];

app.printer = new esri.dijit.Print({
          map: app.map,
    templates: [{
    label: "Layout",
    format: "JPG",
    layout: "Letter ANSI A Landscape",
    preserveScale: false,
    layoutOptions: {
      titleText: "My Print",
      authorText: "esri",
      copyrightText: "My Company",
      scalebarUnit: "Miles",
                                  legendLayer: myLegendLayer
    }
     }
    ],
          url: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task"
        }, dojo.byId("printButton"));

Thanks, John, for the quick reply. However I can't get to that point.

Just this line of code by itself.....var legendLayer = new esri.tasks.LegendLayer();.....bombs the app.

Thanks!

where are you placing that line?
can you post a sample application?

Let me re-phrase. It doesn't bomb the entire app but rather the "handlePrintInfo" function.

Problem code is in bold italic

Thanks!

function handlePrintInfo(resp) {
        var layoutTemplate, templateNames, mapOnlyIndex, templates; 

        layoutTemplate = dojo.filter(resp.parameters, function(param, idx) {
          return param.name === "Layout_Template";
        });
       
        if ( layoutTemplate.length == 0 ) {
          console.log("print service parameters name for templates must be \"Layout_Template\"");
          return;
        }
        templateNames = layoutTemplate[0].choiceList;

        // remove the MAP_ONLY template then add it to the end of the list of templates
        mapOnlyIndex = dojo.indexOf(templateNames, "MAP_ONLY");
        if ( mapOnlyIndex > -1 ) {
          var mapOnly = templateNames.splice(mapOnlyIndex, mapOnlyIndex + 1)[0];
          templateNames.push(mapOnly);
        }

       
        // create a print template for each choice
          templates = dojo.map(templateNames, function(ch) {         
          var plate = new esri.tasks.PrintTemplate();

          var legendLayer = new esri.tasks.LegendLayer();


          plate.layout = plate.label = ch;
          plate.format = "PDF";
          plate.layoutOptions = {
            "authorText": "City of Fort Smith GIS",
            "copyrightText": "Copyright 2012, Fort Smith GIS",
            "legendLayers": [0,1,2,3],
            "titleText": "Chaffee Crossing",
            "scalebarUnit": "Feet"
          };
          return plate;
        });

heres a working jsfiddle (just update reference to use your own proxy)

var poolFeatureLayer = new esri.layers.FeatureLayer(permitUrl, {           "mode": esri.layers.FeatureLayer.MODE_SNAPSHOT,               //make sure the layer you wish to add to the legend includes an id to pass to legendLayers           "id": "PoolPermits"         });  // create a print template for each choice         templates = dojo.map(templateNames, function(ch) {           var plate = new esri.tasks.PrintTemplate();    var legendLayer = new esri.tasks.LegendLayer();    //set the layerId property for legendLayer           legendLayer.layerId = "PoolPermits";     //legendLayer.subLayerIds = [];         plate.layout = plate.label = ch;           plate.format = "PDF";           plate.layoutOptions = {              "authorText": "May by:  Esri's JS API Team",             "copyrightText": "<copyright info here>",             "titleText": "Pool Permits",              "scalebarUnit": "Miles",                          //this property needs to be set with an array of legendLayer objects, not layerIds      "legendLayers": [legendLayer],            };           return plate;         });

Once again, thanks John.

However that line of code mentioned above var legendLayer = new esri.tasks.LegendLayer(); isn't agreeable anywhere in my application for some reason. The error is "called_non_callable".

If I place that line of code, and only that single line of code, into the otherwise working sample, it bombs.

Ugh....figured it out, John.

I had forgotten to include. Still trying to use the 2.7.

if you can post a sample app, i would be happy to take a look.
