Hello!
When I create a ArcGIS Online writer and want to add a GlobalID as an attribute, the type to choose is
esriFieldTypeGlobalID but FME doesn't offer me this choice.
In the log I can see this message :
"ArcGIS Online Feature Service Writer: Attribute 'GlobalID' on feature type 'Frenes' has type 'esriFieldTypeOID', but the type on the server is 'esriFieldTypeGlobalID'"
I think FME should add this field type.
Thanks!
