Sure. Here is the "bad code". I already posted the good code in another response. I ensure you that the "where" and "url" lines are identical in both good and bad code since I copied and pasted.

Thanks. I agree, however the issue persists even after the correction. The strange thing is that the Good code even though has the same incorrect evaluation (attr = "Odometer"), it does work by providing a response with the correct value.

‎07-01-2015

Actually, no. I get a response with the correct value. Thanks. Here is the complete good code, modified from one of the samples in the esri's JS API website. <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8">  <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <title>Query State Info without Map</title> <script src="http://js.arcgis.com/3.13/"></script> <script> require([ "dojo/dom", "dojo/on", "esri/tasks/query", "esri/tasks/QueryTask", "dojo/domReady!" ], function (dom, on, Query, QueryTask) { var queryTask = new QueryTask("<place you url>); var query = new Query(); query.returnGeometry = false; query.outFields = ["Odometer"]; on(dom.byId("execute"), "click", execute); function execute () { query.where = <place your condition> ; queryTask.execute(query, showResults); } function showResults (results) { var resultItems = []; var resultCount = results.features.length; alert (resultCount); for (var i = 0; i < resultCount; i++) { var featureAttributes = results.features.attributes; for (var attr in featureAttributes) { if (attr = "Odometer") { alert(attr + "1: " + featureAttributes[attr]); resultItems.push("<b>" + attr + ":</b> " + featureAttributes[attr] + "<br>"); } resultItems.push("<br>"); } } // dom.byId("info").innerHTML = resultItems.join(""); } }); </script> </head> <body> US state name : <input type="text" id="stateName" value="474"> <input id="execute" type="button" value="Get Details"> <br /> <br /> <div id="info" style="padding:5px; margin:5px; background-color:#eee;"> </div> </body> </html>

This function returns undefined variable. The first alert returns: something found:1 the second alert returns "Odometer 1: undefined. I have a very similar code shown below under GOOD CODE that it returns the expected value. Both code execute the same querytask. What's wrong in the first block code? Thanks. function queryTask_odometer1_executeCompleteHandler(results) { if (results.features && results.features.length > 0) { alert("something found: " + results.features.length); resultCount=results.features.length; for (var i = 0; i < resultCount; i++) { var featureAttributes = results.features.attributes; for (var attr in featureAttributes) { if (attr = "Odometer") { alert(attr + "1: " + featureAttributes[attr]); } } } }else{ alert("nothing found"); } //alert(mydata); } GOOD CODE function showResults (results) { var resultItems = []; var resultCount = results.features.length; alert (resultCount); for (var i = 0; i < resultCount; i++) { var featureAttributes = results.features.attributes; for (var attr in featureAttributes) { if (attr = "Odometer") { alert(attr + "1: " + featureAttributes[attr]); resultItems.push("<b>" + attr + ":</b> " + featureAttributes[attr] + "<br>"); } } } // dom.byId("info").innerHTML = resultI

Can you elaborate?

‎06-23-2015

I tested that. Unfortunately, after I copied the app folder, the app is not showing in the WAB developer listing of apps. I also tried to zip it and import it, but it says invalid app.

When I was coding in Flex, I was able to package the libraries and code (export flash builder project) in a single file (fxp) at work and import in at home's flash builder to continue working on my projects. Is there are any similar process with WAB? Can I install WAB at two locations and copy the app folder from one location to paste it at another location to continue working on my project? Thank you.

ok, I solved the mystery. I finally got the LocalLayer in the configs folder. The instructions that comes with the LocalLayer widget says to add the reference to the widget in: "open the client\stemapp\themes\TabTheme\layouts\default\config.json in a text editor...." However, Rebecca's "Web AppBuilder Developer Edition–Customization Resource List" correctly points out to add the reference in default AND layout1 folders. That made the difference. I guess I learnt two lessons. Do not add customized widgets unless you add one ESRI's widget first to initiate creation of the configs folder. Second, Read Rebecca's list. THANK YOU Robert and Rebecca for your time.

The problem is that there is no LocalLayer folder in the configs folder. This is the steps from the beginning. 1. Install the LocalLayer in the appbuilder 1.1 and performed the json modifications per instructions. 2. Created new app. The LocalLayer widget is visible in the widgets area. 3. Added bookmark widget and saved map. The configs folder is now visible. 4. Customized the LocalLayers to include a feature service. I don't know how to include the LocalLayer in the configs folder to apply Robert's code to implement definitionExpression. Ideas? Thank you.

‎06-03-2015

Yes, is there now. I have bookmark widget under the new folder configs and one under the widgets folder. When I created the other app, I didn't add any widgets and I just installed the LocalLayer by following the instructions. In the LocalLayer instructions there is no mention of the configs folder. By not installing any of the ESRI's widgets, I guess the configs folder will not be created. I think the instructions for the LocalLayer should reflect the fact that if this is the first widget to be installed, that the configs folder will not be created. Please let me know if I am mis-reading the situation. Thank you.

‎06-03-2015

No, everything is new. I just started the migration from flex and I am new on web appbuilder. So, I downloaded the 1.1 from the esri website and create the app. Everything went without a glitch until you made me aware of the missing folder. I am wondering how many other users are missing the folder and don't know about it. Is there another site (like github) that I can download the 1.1 and I will re-create the app to check if the config folder exist? Thank you.

‎06-02-2015

ok, this is bizarre. I reinstalled the 1.1 version and still the configs folder is not there!!!!

‎06-02-2015

Well that's weird. I downloaded the arcgis-web-appbuilder-1.1.zip file from the website and the filename indicates is the 1.1 version. when you unzip, the buildnum.txt shows the build number as : 2015-03-16_18-39-33_#354 Is this the 1.1 version?

‎06-02-2015

You mean: C:\arcgis-web-appbuilder-1.1\server\apps\4\widgets\LocalLayer? Yes, I do. There is no configs folder under the app id.

‎06-02-2015

Robert, the widget.js script I posted is indeed from the response marked as answer. and I changed the json to: "definitionExpression": "DIST=10", but still no filtering. Thanks.
