AnyOf/OneOf complex object cannot be rendered

[eholman]

I had a schema that used to work in the Developer portal until there was an array of complex objects added.

My schema is valid (checked on editor.swagger.io) but when I'm using a complex object in an AnyOf or OneOf it cannot be rendered because the map() method cannot be found on an undefined object

I've also tried to use the $ref notation but it doesn't help.

Any suggestions what might help to get the rendering fixed?

Many thanks in advance!
