outSpatialReference

[RobertMyers]

Is it possible to enter the wkid of 102100 instead of {myMap.spatialReference} in the outSpatialReference for a query?

Code:  outSpatialReference="{myMap.spatialReference}" 

Wrong: outSpatialReference="102100" 

Thanks

You want to create a new SpatialReference
http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/SpatialReference.html

so it would look like
query.outSpatialReference = new com.esri.ags.SpatialRefence(102100);
