Hello Jesper.
I think I am also trying to find the answer to this (Retrieving the alias of a block in a custom property editor)
I have been trying to look through the different Context’s that are available, but so far I can’t find out what I need to use to get the alias of the block that you’re currently editing.
I am hoping it’ll be slightly easier for us to find, because in previous versions (13), I was having to do this:
"let alias = $scope.$parent.$parent.$parent.$parent.$parent.$parent.$parent.$parent.$parent.$parent.$parent.model.content.contentTypeAlias;"
Will let you know if I find anything.
Thanks,
Rob
