Invisible primary key

I'm getting the primary key problem (I've read TW doesn't seem to recognize primary key, btw).

The primary key definition from Schema for my import table is:

  'primary key' => array('Array'),

which is clearly cackked given that all the other ones look something like:

  'primary key' => array('did'),

Since you depend on Schema it's looking like the problem is over there, not in TW.
