[Rubycocoa-talk] Binding to extended keyPath supported?

[Ferhat A. <fer...@ya...>]

Hi,


sorry if I bother the list. I get an error when I try to bind a keypath like field1.childField


Here is the simple code


class Cashier < ActiveRecord::Base

end



class Product < ActiveRecord::Base

  belongs_to :cashier

end


The cashier has a field 'realname'. When I now try to bind a tablecolumn to an ActiveRecordSetController arraycontroller with ProductProxy content by using the key path 'cashier.realname', the application produces the following error message


OSX::OCException: NSInternalInconsistencyException - Cannot remove an observer <NSTableBinder 0x1a430a0> for the key path "cashier.realname" from <ProductProxy 0x21c66d0>, most likely because the value for the key "cashier" has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the ProductProxy class.


Do you have any idea? I tried to add kvc_accessor unfortunately without success


class ProductProxy < OSX::ActiveRecordProxy
   kvc_accessor :cashier

end


Thanks for any help
Ferhat
