Well, let's take a look at it:
{item =
{values =
values is internal dictionary in an EOGenericRecord. It is good that you
can't get this.
{attr1 = "Adult Male";
I'm reasonably certain that selling people is not legal in most countries.
AFAIK, the practice has been largely abandoned.
attr2 = <com.webobjects.foundation.NSKeyValueCoding$Null>;
attr3 = <com.webobjects.foundation.NSKeyValueCoding$Null>;
attr4 = <com.webobjects.foundation.NSKeyValueCoding$Null>;
attr5 = <com.webobjects.foundation.NSKeyValueCoding$Null>;
productid = "AV-SB-02";
listPrice = 15.000000000000000000000000000000;
supplier = "<com.webobjects.eocontrol.EOGenericRecord 50988>
(com.webobjects.eoaccess.EOAccessFaultHandler
_EOIntegralKeyGlobalID[Supplier (java.lang.Integer)1])>";
itemid = "EST-19";
product = "<com.webobjectsexamples.petstore.Product 941f7
_EOVectorKeyGlobalID[Product (java.lang.String)AV-SB-02]>";
unitCost = 2.000000000000000000000000000000;
status = "P";
inventory = "<com.webobjectsexamples.petstore.Inventory 34e29b
_EOVectorKeyGlobalID[Inventory (java.lang.String)EST-19]>"; };
this = "<com.webobjectsexamples.petstore.Item 7a1576
_EOVectorKeyGlobalID[Item (java.lang.String)EST-19]>"; };
So item is an object of type Item.
total = 30.0;
qty = 3; }
I see no itemPrice. Do you? Did you perhaps mean listPrice?
Yes sorry, I was writting before thinking
Spelling counts in KVC as in many aspects of life. :-P
Yes I know and I did write the correct key in the path and still could not
get the value... wait just did it again and got the value... I can't believe
that, I must have been writting in the wrong key all along. Dah
Thank for your time Chuck

I want to be able to get the itemPrice value out of this dictionary so I'm
using valueForKeyPath("item.itemPrice") and I've even used
valueForKeyPath("item.values.itemPrice") but I just get the exception
