ERRest skipping my NSDictionary

Hi all,

This is an ERRest specific question.

I have an iOS -> WebObjects/ERRest setup regularly working.
One of the entities on both sides has an attribute that returns an NSDictionary.
The problem is that when I try to update this attribute from the iOS side into the WO side, it is silently skipped and left empty.

The iOS side JSON-serializes everything before posting the Rest requests… as a result, the dictionary attribute shows in the JSON output, very similar to a relationship child node.

I could be saying something stupid here so please don’t be too harsh…

The thing is, together with any primitive type, I was assuming that the Map/Dictionary kind was among the things I could “obviously” send.
Now I’m not so sure… could anybody shed some light on this, since I could be banging my head under the wrong tree?

In other words… Can I send a Map/Dictionary type object inside my JSON request and hope that WO/ERRest will catch that it is NOT a relationship to other nodes, but simply a plain old dictionary and call my entity setter or am I simply confusing ERRest?

BTW, not sure if it means anything, but the attribute is actually a class method and not a real model attribute since the dictionary needs to be processed. Could that be the issue?

Please help,
Riccardo De Menna
