Are you attempting to upgrade from version 2.x?  If so, you should read "Migrating to 3.0" documention at http://help.arcgis.com/en/webapi/javascript/arcgis/help/jshelp_start.htm. ... View more

You're still not waiting for the response to be done before proceeding.  You could do what your trying to do by nesting the second step inside a callback function: function getProjectReport(theFid) {   var theDocument, theGraphic     returnTipShape(theFid,function(returnedShape){     console.log(theGraphic.attributes.PROJECT);         .         .         .   });     } function returnTipShape(param,callback) {   var theParam = param.split(",");   var query = new esri.tasks.Query();      query.where = "FID=" + theParam[0];   query.outFields = ["*"];   query.returnGeometry = true;   var theShape;     //Specify the appropriate point/line map service depending on what was clicked   switch (theParam[1]) {     case "point":       var queryTask = new esri.tasks.QueryTask("http://dmc-arcgis.snoco.co.snohomish.wa.us/SnocoGISdev/rest/services/transportation/tipProjectsPoint/MapServer/0");         break;     case "polyline":       var queryTask = new esri.tasks.QueryTask("http://dmc-arcgis.snoco.co.snohomish.wa.us/SnocoGISdev/rest/services/transportation/tipProjectsLine/MapServer/0");          break;   }   dQuery = queryTask.execute(query);   var dList = new dojo.DeferredList([dQuery]);   dList.then(function(results) {     var featureSet = results[0];     dojo.forEach(featureSet.features, function(feature) {         theShape = feature;               });     callback(theShape);   });     //return theShape; } Also, you don't really need a deferredList in this case since you're only doing one call.  Deferred lists are really only necessary when you need to wait for the response from multiples requests. ...

You're passing the graphic to the console before the execute task has finished running.  Place the console.log inside the callback for the execute function. queryTask.execute(query,function(featureSet) {    dojo.forEach(featureSet.features, function(feature) {      theGraphic = feature;                       });                 console.log(theGraphic.attributes.PROJECT); }); Just FYI, based on the above code, theGraphic is only going to represent the last item in the featureSet. ...

We use the following to handle any url parameters:     //fetch any parameters that were passed with the url var urlParams = esri.urlToObject(document.location.href).query || {};     //convert each url parameter from a string to a javascript object   for (var prop in urlParams) {   if (urlParams.hasOwnProperty(prop)) {     try {       urlParams[prop] = dojo.fromJson(urlParams[prop]);     }     catch (err) {        //ignore the error     }   } } If you pass your layers as an array (i.e. layers=[0,1,2,3,4]), you should be good to go.  Each parameter will end up as a property of the urlParams object. ...

We abandoned ESRI's infoWindow awhile back. As a replacement, we've been using dojo floatingPanes.  You can use as many you need and the user can move them around the page. Here is an example if you're interested:http://fwp.mt.gov/gis/maps/huntPlanner/ ... View more

Here is my latest installment.  I linked to the onClick event of the basemapGallery Nodes:     //Listen for a change of basemap (NIM080755)     dojo.forEach(dojo.query(".esriBasemapGalleryNode"),function(galleryNode){       dojo.connect(galleryNode,"onclick",function(){         _this._basemapButton.closeDropDown();         _this._disableAllMapFunctionUntilBasemapUpdates();       });     }); The following function disables the map until it is done updating: //this is a a stopgap measure until ESRI fixes NIM080755    _disableAllMapFunctionUntilBasemapUpdates: function(){     var _this = this;     //disable the map  it id done updating the basemap     var mapStandby = new dojox.widget.Standby({target: _this.map.container});     document.body.appendChild(mapStandby.domNode);     mapStandby.startup();     mapStandby.show();         var mapUpdateEndConnect = dojo.connect(_this.map,"onUpdateEnd",function(){         mapStandby.destroy();         dojo.disconnect(mapUpdateEndConnect);       });      } Finally, if all else fails I give the user an alert so they know something might have gone wrong.  //added to account for errors caused by NIM080755     window.onerror = function(){       alert("An error has occured.\nYou're map will likely continue to function, but you may see inconsistent results.\nRefresh your browser to start over.");     }; ...

One way to do this is to search all map layers and look for the "_basemapGalleryLayerType" property.  If it is set to "basemap", then you can simply hide the layer.  It works in 2.2.  I haven't tried it with the other versions of the API, so I'm not sure if the "_basemapGalleryLayerType" property is always available or not. Here's what my function looks like: hideBaseMap: function(){     var _this = this;     dojo.forEach(this.map.layerIds, function(id){       var layer = _this.map.getLayer(id);       if (layer._basemapGalleryLayerType === "basemap") {         layer.hide()       }     });   } ...

The following seems to work: var noBaseMap = new esri.dijit.Basemap({       layers:[],       title:"None",       thumbnailUrl:"images/none.jpg"     });   basemaps.push(noBaseMap); ... View more

The response from the sample profile service is a picture, not actual elevation values.  Here is a sample usage. If you want to perform your own analysis (or create your own graph) you will need to access some elevation data directly. I'm not sure what the best source would be.  ESRI host a globe service at  \\fwphlncmstst001\gis  but I don't think this is queryable via javascript.  Google host elevation data, but I don't know if you use it outside of the google maps API.  Any other suggestions? ...

The following forum pointed me in the right direction.  http://forums.arcgis.com/threads/19233-Token-used-in-proxy-not-working-for-Feature-Service (this forum is related to flex, but I assume it still applies conceptually). The fact that the referring URL is set correctly doesn't matter since... "When you generate the token, you should use the IP address of the proxy machine as seen by the ArcGIS Server. This is because the referer header is not passed on by the proxy." I'm not using thet IP address method because I'm embedding the token in the application.  We tried embedding the token in the proxy page originally.  This worked OK, but we had performance problems on our application (JBOSS) when we started doing load tests.  Generating a single token for a user's session and embedding it in the application took care of this problem for us.  But now I need the proxy page again. How can I embed the a token in a application and still retain the ability to use the proxy page for "long-winded" requests? ... View more

I understand why the request is going through the proxy page, but I still can't figure out why I'm getting an invalid token response.  I just checked, and my referrer is set to the same for the get and the post requests (the "Host" is different, but I don't see why this would be relevant). ...
