In Sharepoint for ArcGIS, I'm having trouble populating the attribute dropdown for varying symbology by attribute. When connecting to a sharepoint photo library with a prepopulated field for the direction of rotation, the atrribute dropdown in the map webpart does not recognize any sharepoint fields when the values are formatted as either a string or number. Should I use to use a different format for the sharepoint value? Is it possible to vary symbology rotation by a sharepoint field in ArcGIS for Sharepoint or should I go about this a different way?
