Problem with Graphics Layer

NigelAlford — Fri, 04 May 2012 19:21:22 GMT

I'm using the graphics layer example and one query works but the second doesn't and I'm stuck on the reason why. Both layers support Querying and the specified query works inside the service. I run a console log for both queries and I'm getting an error message:

ReferenceError
arguments: Array[1]
get message: function () { [native code] }
get stack: function () { [native code] }
set message: function () { [native code] }
set stack: function () { [native code] }
type: "not_defined"
__proto__: Error
 serverapi.arcgisonline.com:14
dojo.Deferred.reject.errback

Below is the code for the map:

In your locomotive query, you need to change the last line

from:

 MPQueryTask.execute(LocQuery, LocSymbology);

to:

LocQueryTask.execute(LocQuery, LocSymbology);

think you forgot to change it to the locomotive query task after you c/p it
