Hi dojo,

I have the following field descriptors:

My end goal is to retrieve the entries to get the display names used.

The first one, I can cast as a GenericEnumFieldDescriptor.
The issue is, I can’t cast the second one (The services impactés). Just doing something simple like:

var generic = (GenericEnumFieldDescriptor)descriptor;
var dropdownOptions = generic.GenericEnumInstance.Entries;

I’m getting:

System.InvalidCastException: Unable to cast object of type ‘Skyline.DataMiner.Net.Sections.FieldDescriptor’ to type ‘Skyline.DataMiner.Net.Sections.GenericEnumFieldDescriptor’.

Hi Ana, to investigate this further you could log the value of "descriptor.GetType().FullName". This will give you the actual runtime type of descriptor.
