Hi Flex Gurus,

I need a small favor. I am working on a dropdown control and zoom to feature (point) for a beach application. I was able to implement the attached code alright for a standalone application. But, When I am adding the code as a custom widget to my existing code....I am getting the following error. That is, Could not resolve <s:controlBarContent> to a component implementation. I attached the code as well as error image here. Could you please help me fix the issue. Please let me know if you need further information. Many thanks for your help.

Thanks,

Sam,

No that is not the issue because I build the exact code I sent you using Flash Builder 4.5 and the 4.5 SDK as well. See what happens when you fully qualify the query in the init function.

protected function init():void
   {
    var query:com.esri.ags.tasks.supportClasses.Query = new com.esri.ags.tasks.supportClasses.Query();
    query.outFields = [ "NAME_1" ];
    query.outSpatialReference = map.spatialReference;
    query.returnGeometry = true;
    query.where = "1=1";
    queryTask.execute(query);
   }

Ok. Thanks for your continued support. I am new to Flex development. Previously, I was working with Silverlight API. I hear some compatibility issues with Flash Builder 4.5. Should I go back to Flash Builder 4.0?

Thanks,
Sam

Sam,

The issue I am having is that because the code already has:

import com.esri.ags.tasks.supportClasses.Query;

There is no reason for that error if you are using agslib-2.3.1-2011-04-26...

Robert,

I am using agslib-2.3.1-2011-04-26.

Sam,

What ESRI Flex API version are you using?

Hi Robert,

Thanks for your help. I appreciate it. I was able to get past that error. But, I have another issue facing me. That is, call to a undefined method query. I attached the error file. The error is showing up in init() function for method Query. Your help is appreciated.
