Yes seems like your getting a reference to myPopulateCodeList.codeList.  If your going to store those codeLists in the global scope then I would recommend modifying the module a little so codeList is not a property of myPopulateCodeList to prevent issues like this.  Here is an example of the original sample I posted with some changes to make codeList not a property of myPopulateCodeList module. define([      "dojo/on",      "esri/tasks/QueryTask",      "esri/tasks/query",      "dojo/_base/lang",    "dojo/Deferred"      ], function(      on, QueryTask, Query, lang, Deferred){      var mo = {        //codeList: [],   We don't want this as a property here, it should be a local variable in function below      populateCode: function(codeType, url){          var codeAtt, specAtt, codeList = [];  // Added local codeList here       var deferred = new Deferred();          switch (codeType) {            case "spec":              codeAtt = "ID_SPECIALTY_PK";              specAtt = "TX_SPECIALTY_DESC";              break;            default:              codeAtt = "ID_PROV_TYPE_PK";              specAtt = "TX_PROV_DESC";              break;          }          var queryTask = new QueryTask(url);          var query = new Query();          query.outFields = ["*"];          query.where = "1=1";          query.returnGeometry = false;          queryTask.execute(query, lang.hitch(this,function(results){            var numResults = results.featureSet.features.length;            for (var j = 0; j < numResults; j++) {              var code = results.featureSet.features .attributes[codeAtt];              var desc = results.featureSet.features .attributes[specAtt];           // push to the local codeList and not this.codeList             codeList.push({                code: code,                desc: desc              });            }            console.log("end of codeList array build");           deferred.resolve(codeList);        }), function(err){            console.log("error in myPopulateCodeList, error: " + err.details);          deferred.reject(err);          });         return deferred;       }      };      return mo;    });  What was happening was that when you called the populateCode function, it was updating the myPopulateCodeList.codeList property. So when you call populateCode function it just updates the same property no matter what you pass into it.  Doing it this way returns a new codeList each time and then you can append it to your global codeLists ...

Couple Things.   You may want to read up on a AMD tutorial for Dojo or for Esri.  When you put a function inside another function(aka your beginmeasure function inside the callback for require) it is not available globally.  So that is why the code is throwing an error. Another thing is how to attach events in dojo.  I recommend looking up how to use the dojo/on module (dojo/on view /dojo/on).  It is perfect for attaching events.  The way it works is you import the module via the require function, and then in your code you will call something like on(document.getElementById("measurearea"), "click", function () {   // Run your code here }); what that is doing is saying on, the measurearea button click event, call my function.  This will allow you to listen to the button click event. Lastly you will want to look up the draw tools.  They created the Draw toolbar, and attached the event for you and you don't want to change that part.  What you want to do is on click, activate the toolbar, and then on draw end, run the getAreaAndLength function and deactivate the toolbar so for example: on(document.getElementById("measurearea"), "click", function () { tb.activate(Draw.FREEHAND_POLYGON); }); and then in the getAreasAndLength function you will need to call tb.deactivate(); This way, map.on('load') the Draw toolbar is created, the function to get the areasAndLengths is attached to draw-end and ready to go.  And then when the button is clicked, you can activate the toolbar.  When they finish drawing, it will trigger the getAreasAndLength function and then you can deactivate the toolbar. Your going to need to get familiar with the AMD style of JavaScript programming to work with most of the samples. ... View more

Ok never mind the question, I started messing with some of the tiled layer functions and finally made it work.  Looks like calling this.onLoad(this) after I updated the initial and fullExtent caused the layer to reset those values and I am now no longer getting 404 errors. ... View more
