Json schema nested array properties incorectly mapped.

[Adam-Michalski]

Description
Json schema nested array properties incorectly mapped in array on second level (don't know what happens deeper).
At first level in root array we can see that hidden property is correctly mapped and age is not displayed for two of three elements but on the second array with hidden property specified exacly the same like in root array age is displayed.

You can observe that mapFn param mapSource passed to map for every field is passed (as it seams) as first element from second level array properties.
