[MacRuby-devel] TableView dataSource doesn't work

[Laurent Sansonetti]

Hi Satoshi-san!

I added support for that in trunk a few days ago. But the changes have  
not been merged into the testing branch yet (I plan to do that as soon  
as possible).

Did you try testing or trunk? In my environment (trunk), your sample  
works great.
