How to create dependent enumeration as attribute type in DNG?
Accepted answer
To be sure I understand your question: at runtime when editing an artifact, the values available to select from for the second enumeration attribute are limited based on the value chosen for the first enumeration attribute?
If that is the question, the answer is that DNG does not support such functionality right now.
If you feel DNG should have this functionality, feel free to put in a request for enhancement, which you can do here: IBM Software RFE Community
Make sure you describe your use case in sufficient detail. For example what to do if the first enumeration does not have a default value, and at runtime no value is selected for the first enumeration attribute for the artifact under edit.
