My current build is 1509.
I am trying to enable OData for native property "Children" in a non-native class which inherites from Native.HierarchicalFolder. When I run full rebuild I get an error (see screenshot 1). If I ignore the error and continue with the rebuild, then I get the error seen in screenshot 2.
I have also tried to change the parent class (HierarchicalFolder) and enable "OData read access" in settings, and changing the Children property by using the button "Change existing property". This didn't work either, same error. Even if it did work, it wouldn't help me much. Because, what I'm trying to achieve is to enable OData access to the children of the new class which I have created for this purpose, not for all folders (nodes of type HierarchicalFolder).
However, enabling OData for non-native properties in the same class works fine, and I can also see their values in the OData stream.
