Hello
We have a custom field (Primary Service/customField_10455) which has the following configuration:

In a different Object schema we have an object type "Solution Configuration Item" which has a Service property as an outbound reference to Services.
We then have another custom field (Solution Modules/customField_10440) which has the following configuration:

The above configuration never return any values even when the Primary Service field has a service selected that does have Solution Configuration Item defined.
If we replace the ${customField_10455} with the actual Key as shown below it returns the expected values:

We have spent hours trying all different kinds of permutations but nothing gives us the result we are looking for which is a filtered Solution Modules selection list based on the selected Primary Service.
Any inputs would be greatly appreciated.
Thanks
Atle
