Hi Olivier,
I can't tell what you're doing from the snippet of code you sent.
I'm still on WO 5.1, but at least in this version, I can tell from looking through the Java browser that _EOCheapCopyMutableArray does extend NSMutableArray (which in turn extends NSArray). So you shouldn't have any problems--or class cast exceptions--if you program to the NSArray interface. In other words, an _EOCheapCopyMutableArray is an NSArray and can be treated as such.
Just for background, these "cheap copy arrays" are array faults; they're stand-ins for to-many relationships before the relationship fault has been fired and related objects are fetched from the database.
This may have changed in WO 5.2, I don't know.

Hy,
i have some problems with EOCheapCopyMutableArray to reading result of relationship.
object = storedValueforKey("relationshipKey");
if(object instanceof NSArray)
{
if((NSArray)object).count()==0)
i try this code but i have a java.lang.ClassCastException for cast on NSArray
Do you have a another methods to read EOCheapCopyMutableArray??
