[MacRuby-devel] TableView dataSource doesn't work

[Satoshi Nakagawa]

Hi,

I have tried to use NSTableView.
In it's dataSource, tableView(table, objectValueForTableColumn:col,  
row:row) crashed while numberOfRowsInTableView seemed working well.

class AppController < NSObject
   def numberOfRowsInTableView(sender)
     puts 'numberOfRowsInTableView'
     10
   end

   def tableView(table, objectValueForTableColumn:col, row:row)
     puts 'tableView:objectValueForTableColumn:row:'
     'test'
   end
end
