List View and Table View don't work on canvas page

Hi, I read the README.txt from start to finish, and followed point by point all instructions.
I am able to create the application.
I am having issues with views.
I have content types with different fields, and I am creating a custom view which selects only some fields.
I am trying both list view and table view.
But when I access the canvas page on fb (I set it to point to my view) I get a list of drupal error/warning like

"Invalid argument supplied for foreach() in /srv/www/htdocs/festival/sites/all/modules/cck/content_views.inc on line 192."

And my list/table only shows the title of the nodes.
It's like views is not able to pull the fields.

Can you help me? Am I supposed to not use List View or Table View?

Thanks in advance,
GP
