While layers get linked properly, layer group have the name but miss the link to the group.
This happens in all series.
I believe this is fixed for 2.12 rest-api-refresh
Jody I'm looking at the postEncodeReference in the LayerGroupController, I don't see treatment of nested layer groups in there.
Tests show nested layer group creation, but no usage of get method to check the xml encoding output.
I can confirm that this also affects 2.12 post rest-api-refresh
