I'm using ArcGiS 10 and AGX 1200. When I author a layer package in ArcMap, I set the primary display field, which should control the title of the popup in AGX. However, when I load the layer package in AGX, the popup title seems to revert to the objectID, and does not use the display field I selected.
From reading the forums, I found that you can work around this by creating an attribute field called "Name", and then filling it with your primary display field. Apparently AGX automatically finds this field and uses it as the display field, whether you want it or not. It's a viable workaround, but not ideal.
Is this a known bug?
