Illustrator SDK :: AICS6 - Dictionary Not Saved / Different ArtHandle?

when trying to set an entry value in an art object's dictionary with AICS6 SDK. I have a native winow handler set on a toolbar where I have set a few buttons.
 
When I click on the "Outline" button, it is supposed to set an entry (named "FB_CurveType") in the dictionary of the selected art object.
 
newKey = pAIDictionary->Key("FB_CurveType");
pAIArt->GetDictionary(hArt, &dataDict);
pAIDictionary->SetIntegerEntry(dataDict, newKey, type);

[Code]....
 
The returned art handle is valid (not NULL) and I can successfully set the value, and re read it immediatly after setting it (even when disposing/re-getting a reference to the dictionary).
 
The problem comes when I click on "Get Data", it is supposed to loop through each art handle in the document, and check if it has an entry called "FB_CurveType" in its dictionary. Unfortunately, the returned Art Handle's dictionary is empty, and no error code is returned by the SDK functions.I have also noticed that the art handle's value is not the same as the one in the selection code above, at first I thought "Well, maybe that's because Illustrator returns some dynamicaly allocated pointer or something", but when I'm clicking on "Outline" again, the art handle's value is the same as the one in the previous call.
 
My guess is that my function to get all the art objects in the document makes an older or a pale copy of the real art object. Here is the function :
 
void GetArtsByType(AIArtType artType, AIArtSet set)
{
AIArtSpec specs[1];
