[aerogear-dev] [aerogear-ios] error on store save

[Matthias Wessendorf]

Hi Yavuz,

the "problem" is that the 'null' (for telephone on the first object) is, in
Cocoa/ObjC mapped to NSNull. However, NSNull is, unfortunately, not a
"valid" PList object/type.
A work around, on your server, would be to do something like:  "telephone"
=> "NULL", or simply exclude all keys where values are "NULL"... :-/

There are ways how we could fix it on the library:
* exclude every key, where value is NSNull (which makes the value 'nil'
(not NSNull)
* see if new 'store' could be written, that simply
uses NSJSONSerialization, to store JSON on the "filesystem"

I will create a JIRA ticket for this issue.

Thanks for the feedback.
