Map service labels not displayed in flex viewer 3.0

[KurtTowler]

I am hoping someone has run into this kind of weird issue.  I have tried a number of ideas but the web service will not display labels in the ArcGIS Viewer for Flex 3.0.

Javascript viewer:  Labels are visible.
ArcMap:  Labels are visible.
Dynamic service from shapefile in flex viewer:  Not visible.
Dynamic service from SDE:  Not visible.
New webservice hitting different data:  Still not visible.
Flex popups work and attribute data can be seen there.
Chrome/IE - Not visible.
Created Flex App from both Server 2008 R2 and from WinXP - no difference.

Other steps taken:
Reinstalled ArcGIS Server
Reinstalled Adobe Air and ArcGIS Viewer from Flex
Versions 10.1 and Adobe Air 3.4
Most installation steps are the default settings.

Is there something I'm missing?

Thanks for any ideas you might have.
Kurt

Kurt,

   What does your config.xml look like?

[KurtTowler]

This is really out of the box except for adding the operational layer and setting a basemap.

Kurt,

   Here is your issue... A layer of type="feature" does not support labels or annotation. The type needs to be dynamic

<layer type="dynamic" label="Control Devices"  url="http://vmarcserver03:6080/arcgis/rest/services/ControlDevices/MapServer"  visible="true"> <sublayer id="0" popupconfig="popups/PopUp_1.xml" /> </layer>

[KurtTowler]

That was it!  I have looked for different examples of tag formatting on the layer but not found anything that specific. 

It is weirdly frustrating when an out of the box experience doesn't document a very basic idea.  The application builder automatically makes that a feature layer type without telling the user so it's unclear how my choice limited my application.  "I created a map service with labels, ergo if I choose that map service then I would expect to see labels as part of the application."  Perhaps a future ESRI version would ask the user about labeling and change the tag accordingly, or just respect the service properties.

I will have to delve more deeply into the documentation.

Thank you, Robert.

Kurt,

   In Application Builder if you do not choose a layer from the map service (just the map service) than it will add it as dynamic instead of feature.
