Just in case anyone is still reading this thread, I'm going to attack my issue from a slightly different direction. When I look at the D6 version of CCK, in its views.inc file, it creates a field with three main content sections: myfield[field], myfield[filter] and myfield[argument] This makes total sense to me, given that 3 of the 4 places a field is used in the views UI are as a field, argument or filter. There's also reference, but that's a bit different. My issue is that when I have hook_views_data_alter(&$data), the $data array has my field as myfield[table], myfield[filter] and myfield[argument] ---- no [field] section to be seen...or altered. Sooo... I wonder momentarily if the [field] section needs to be created, rather than altered. But then I wonder why that would be...why it would not have a [field] section to start, and I remember that if I do nothing with this field at all, it does display in the view when selected as a field, and then I go for a walk with the dog.
