Almost all of them have, but some have no data.
The only mainlayer that contains data is "Vertikalnivå 2".
The sublayers "RpJuridiskLinje" and "RpOmråde" have several coded domains.
For RpOmråde, the Fields "KOMM", "PLANTYPE", "PLANSTAT", "VERTNIV", "LOVREFERANSE" and "PLANBEST" has coded domains.
I thougth this was a Flexviewer error, but when I check the description links (in the restAPI) for the services, I see that ArcGISserver skips the coded domains for the service with more than 135 layers.
See for the field "KOMM":
Service that do not work: KOMM ( type: esriFieldTypeInteger , alias: KOMM )
Service that work: KOMM ( type: esriFieldTypeInteger , alias: KOMM , Coded Values: [101: 0101 Halden (�?stfold fylke)] , [104: 0104 Moss (�?stfold fylke)] , [105: 0105 Sarpsborg (�?stfold fylke)] , ...427 more... )
They point to the same dataset and are identical in the mxd (ArcMAP).
I think I will forward this error to my software deliverer, but of course, if you have any suggestions, I will be glad.
