Query Question

EmilyLaMunyon — Mon, 22 Nov 2010 16:55:52 GMT

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!

Emily,

This is your issue:

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

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,

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.

Does it matter that I am using Flash 4?

Emily,

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

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!
