Greetings.
I'm having a weird behavior with the bindings and core data.
i'm sure it's the way the bindings are set that causes my problem but
i can not find the answer.
so i'll ask you guy's :)
I have these entities, with these attributes and relationships.
entity: Transactions
attributes: field1, field2
relationship : transactionType
entity: TransactionTypes
attributes: field1, field2
relationship : transaction
In interface builder I have two array controller bound to these
entities,
the tableview columns are bound to the field1 and field2 and
transactionType
the transaction type is bound to a column in the table view with the
keypath, transactionType.field1
witch displays the name of the transaction type properly.
if i set it to just transactionType, i get a crash, i guess because
it's a relationship...
now, in the transactionType column the cell is a combo box, bound to
transactionTypes array. witch gives me
a drop down list of all the transaction Types available.
the problem i get is that if i select a value from that list,
all the transactions that were of the same type of the one i am trying
ti change
get changed as well, not just the one row I am trying to change.
So let's say i have 15 transactions of type DEBIT and i change the
first one ot CREDIT, all the 14 other ones get changed along with it....
does this make any sense?
Sandro.
thank you again.!
