The outSpatialReference property of findParameters is expecting a spatial reference object.  The code below demonstrates the proper syntax. ie: var sr = new esri.SpatialReference({wkid:102100}); //findParams.outSR = sr (incorrect) findParams.outSpatialReference = sr findParameters in the API reference http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/findparameters.htm spatialReference http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/spatialreference.htm ...

The important thing to remember is that you have to make sure that no code makes calls to the esri namespace until after the page has loaded.  Since functions don't run until they are directed to run, this makes them a safe location. As an example, "dojo.addOnLoad(init)" tells your application to fire the init function as soon as dojo indicates that the page is loaded.  calls to esri.* inside init will be fine. ... View more

you mean this sample, correct? http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/mobile_arcgis.html We noticed a couple problems in that sample after updating it to point at a newer version of the compact jQuery library.  The development team is aware of the problem and working on fixing the sample. Sorry for the inconvenience. ... View more

Not sure if you're trying to write something more modular, but you could always look in REST at the scale that corresponds with a particular level for your tiled service and then use it to setMaxScale() on the entire DynamicMapService layer. http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/arcgisdynamicmapservicelayer.htm#setMaxScale ...

I did another quick test and added the following line to the sample and it appears that our Javascript methods for setting scale dependency are working as well. featureLayer.setMaxScale(99999); With a maximum scale of 99999, in conjunction with the minimum scale interpreted from the map service of 100000, the hydrology layer wasn't drawing at all in my tests. If you have any additional details about the error, please let us know. ... View more

I took a look at our Feature Layer On Demand sample (linked below) and when I zoom out, the minimum scale of the Hydrology layer is definitely being honored.  Is the problem you are seeing specific to another drawing mode or a particular map/feature service? http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/fl_ondemand.html ...

You are hoping to change the value used to symbolize a feature already published in a service, correct? I don't know of any redlining techniques, but you could definitely accomplish this by publishing a feature service and allowing people to add new attribute information and change a value which would set different predetermined symbology. The editing sample linked below gives an example of this.  Just click an existing polygon and change its attribute from "passive" to "active" to see its symbology change. http://help.arcgis.com/en/webapi/javascript/arcgis/demos/ed/ed_default_editingwidget.html ...

the first link that i posted is an excellent example of what is returned by a request to geocode a single address (a recordset of AddressCandidates) http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/addresscandidate.htm Typically we loop through the results of a query operation or a geocoding operation and add the results to a graphics collection to draw them on the map, but in your case you would want to pass the results to a GP task which expects a recordset input. I added an attachment which shows what you get when you interrogate the candidates variable after setting a breakpoint in the application.  If your GP service isn't expecting all those properties, you may have some additional work on your hands to remove them using a technique like delete(candidates.score);  Not to mention the fact that the attributes aren't going to be prepopulated with the exact name value pairs you need. all in all, it may not prove to be a shortcut setting thing up this way. ...

I've never tried creating and populating a RecordSet which includes attribute values only, but you should definitely be able to. http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi/featureset.htm here is a really stripped down example of passing attributes to a graphic and then storing the graphic in a recordset //populate your attributes using name value pairs var attr = {"Plant":"Mesa Mint", "Field2:"Value2"}; //graphics doesn't require geometry, symbology or an info window, so you can just pass in attributes var graphic = new esri.Graphic(null,null,attr,null); //create an empty array var features= []; //push in your attributes features.push(graphic); //create your featureSet and push in the feature var featureSet = new esri.tasks.FeatureSet(); featureSet.features = features; as an alternative, since many tasks actually return a recordset, it might also make sense to seperate the geocoding from the rest of your geoprocessing and pass the result from the first rather than creating the recordset from scratch. good luck with the project. ...

I did a quick test and confirmed that basemaps definitely still display in Internet Explorer when the code assist is referenced with a script tag in an application. I used the following sample as the basis of the application and added my script tag directly below the tag referencing our API on line 21. (see below) http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/map_topo.html <script type="text/javascript" src="http://serverapi.arcgisonline.com/jsapi/arcgis/?v=3.1"></script> <script type="text/javascript" src="Assets/scripts/jsapi_vsdoc_v3.js"></script>     <script type="text/javascript">       dojo.require("dijit.layout.BorderContainer");       dojo.require("dijit.layout.ContentPane");       ..... Where did you get this "install.html" file? what is the URL of the basemap which is not displaying? Where are you placing the script tag in your application? ... View more

If you only want to geocode a single address it would probably be more appropriate to work with a geocoding service instead and pass the parameters directly (instead of trying to build a recordset for a geoprocessing service which expects an input table and does batch geocoding.) The sample linked below demonstrates how to pass a value from a textbox control to an address locator which takes a single line input.  You could modify it to pull values from several textboxes and assign them to an address and zipcode field instead. http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/locator_address.html Here is a link to the geocoding service being used.  I often find it helpful to compare and contrast behavior between geocoding services directly in REST when I see problems in my applications. http://tasks.arcgis.com/ArcGIS/rest/services/WorldLocator/GeocodeServer ...
