ArcGIS 10.1 printing tools GP service issue with "unique value renderer"

[SagarNair1]

Hello Everyone,

I have come across an issue with the ArcGIS 10.1 printing tools GP service. I have a map service that has 3 layers, one of them has been symbolized using �??unique value renderer�?� while the others have been symbolized using �??simple renderer�?�. When I execute the task (export web map task), it fails to display the symbol for the layer symbolized using �??unique value renderer�?� in the legend. It displays the symbols for the �??simple renderer�?� successfully.

None of the layers have scale-dependency set and I have tested this using ESRI�??s sample printing tools service
(http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%2...)

Some of the combinations used �??
1. Include all sub-layer IDs in the JSON �?? Fail
2. Include only the sub-layer ID with unique value renderer in the JSON �?? Fail
3. Include only the sub-layer IDs with simple renderer in the JSON �?? Pass
4. Include just one sub-layer ID with simple renderer in the JSON �?? Pass

Also, I have been able to replicate this behavior with ESRI�??s sample data.

Attached are some screenshots of the issue.

Has anyone seen/faced this problem? Any help would be appreciated.

Thanks in advance,
Sagar
