Unfortunately that isn't working for me. Here's some more information I've
discovered about the ERREST problem; it looks like it can't cope with
Collections (List/Map, or ArrayList/HashMap). Perhaps it wants nasty beans?
Below is an example showing it not coping with a dictionary.
'data' is a derived attribute, returning a dictionary, declared as
ERXKey<Object> in the ERXKeyFilter (or NSDictionary), it returns:
"data":{"nil":true}
An NSArray returns:
"data":["stringValue"]}
which is much better. But an array of dictionary gives:
"data":[{"nil":true}]}
So it seems that the JSON converter is having issues with NSDictionary/Hashmap
(I've tried both).
Does anyone have any ideas?
