Query Question

EmilyLaMunyon

Hello,

I am working with the Flex API samples in Flash 4 and am having some problems with a query in which the results are displayed in a table. Everything looks good in the browser, however, when I try to run the query nothing happens. Any insight?

Thanks!

Thanks once again, it worked!

I was using the old samples I guess...where can I find code samples for the Flex API for Flash 4?

Thanks!

Emily,

Yep it matters than you should be doing something like this then:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
      xmlns:s="library://ns.adobe.com/flex/spark"

      xmlns:supportClasses="com.esri.ags.tasks.supportClasses.*">

  <tasks:QueryTask
   id="queryTask"

  <supportClasses:Query
   id="query"

 </fx:Declarations>
  
 <esri:Map id="map">

 </esri:Map>
 
 <s:Panel title="Using Query tasks without maps"> 
  <s:VGroup>
   <s:HGroup verticalAlign="middle">
    <s:Label text="City Name: " /> 
    <s:TextInput id="cityName" text="Holladay" />
    <s:Button label="Get Details" click="queryTask.execute(query);" />
   </s:HGroup>
   <mx:DataGrid id="resultsGrid" dataProvider="{queryTask.executeLastResult.attributes}" visible="{queryTask.executeLastResult != null}" >            
    <mx:columns>                
     <mx:DataGridColumn headerText="City Name" dataField="CITY"/>                
    </mx:columns>        
   </mx:DataGrid>
  </s:VGroup>       
 </s:Panel>
</s:Application>

Does it matter that I am using Flash 4?

Emily,

Maybe it's not getting the changes compiled. I have put your code into a new FlexBuilder 3 app and it functions for me with the small change I suggested.

EmilyLaMunyon

Thanks Robert! I get confused when to add the layer number to the url and when not to.

I made the suggested change and it still seems to not work. I am not sure what is going on, but when I execute the query, nothing happens still and I get a message in the bottom-left browser reading..Transferring data from gis.slco.org for like 15 minutes. Could this have something to do with our server or is it the code?

Thanks so much!

Emily,

This is your issue:

<esri:QueryTask            
  id="queryTask"
  url="http://gis.slco.org/wwwrest/services/public/Surveyor/MapServer/2"/>
