Hi All,
 I am very much new to cocoa.I am facing some problems.

How do you make sure that the function objectValueForTableColumn under the Tableview gets called.

objectValueForTableColumn is an NSTableView data source method, not sure exactly what you mean by 'under the Tableview'


In my application when I try to debug this function, I see debugger never comes here.I searched in the google and saw that we no need to call explcitly.None of the cocadev emails and test application shows explicit call for objectValueForTableColumn .

objectValueForTableColumn is called by the table view when it requires new data from the data source



I would like to add further is that the project I am working on is preoviously build on project builder.

Did it work then?
If so it sounds like the link between the table view and the data source may have broken somehow...


, now I have upgraded it to Xcode 2.3.So not use whether some paritcular thing I need to be done.

Do I need to do some setting change in the xcodeproj file etc.I tried to debug from awakenib function.I guess something silly I am doing.Please help me on this.
Looking forward for your response.

Hope that helps.

Wain
