Live Copy support for DITA documents

Hello,

I want to use Live Copies of the DAM structure to provide documents in different languages. The structure of the dam elements is based on the product catalog of the customer.

• Master
  • Group A
    • Group AA
      • Product
        • Dita Topics
        • Dita Maps
      • Group AB
    • Group B
  • EN
    • ….
  • …

The problem is that I cannot cancel the inheritance of the content for topics and dita maps. Like I can cancel the inheritance in the properties or on a normal AEM page.

I can edit a Live Copy topic. But after the first rollout of the master was done, an exception occurred when I try to save the topic of the Live Copy.

21.02.2022 10:13:47.788 *ERROR* [127.0.0.1 [1645434827785] POST /bin/validatexml HTTP/1.1] com.adobe.fmdita.uuid.concrete.JcrResource Unable to get references for path /content/dam/dita-maps/copy/Overview.dita uuid null

java.lang.NullPointerException: null

               at com.adobe.fmdita.uuid.ReferenceFactory.getReference(ReferenceFactory.java:46) [com.adobe.fmdita.utils:3.8.0]

Is there an intended way to get Live Copies working with dita documents?

Thanks,

Benjamin
