Steps to Reproduce:

• Create new ZObject
• delete Z2K2
• add new key Z2K2
• choose a type, e.g. Z4
• add a key Z4K1
• choose Z6
• add an ID
• select key to add: Z4K2

Status before pressing return:

Status after pressing return:

Actual Results:
The field of the key "identity (Z4K1)" is empty

Expected Results:
The field should continue to have the value that was entered before.

Note: the actual value, as can be expected in the raw JSON printed below, is retained, and I can save the object at the end, but the editing view does not correctly display the value while editing other fields.
