ha!
what i found out is that since i'm using the transactionType.name to
display the value of the relationship
instead of updating the relationship to that row, the bindings update
the name of the transactionType item
in the database, so all the rows using that use that item also get
renamed, well because the reference object got renamed.
how do i get it to update the relationship instead of just updating
the display name.

I have these entities, with these attributes and relationships.

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....
When the column's cell is a combo box cell, the column has 3
bindings instead of 1 (content, contentValues and value). What are
your bindings set to?. It's not going to work properly unless you
you set all 3 bindings properly.
Also, make sure you set the bindings of the column, not the cell.
