list:reference with SQLFORM.grid

[villas]

Hi All,

Can someone see what the problem is please?

db.define_table('tag', Field('name'))    
db.define_table('test',Field('name'),Field('tags','list:reference tag'))

def test():    
    grid = SQLFORM.grid(db.test, user_signature = False)
    return dict(grid=grid)

Navigate to function test,  try using the grid. Save a record etc and view it.....

Traceback (most recent call last):

Hi Paolo,
Many thanks for looking into this.
I updated earlier this weekend with git pull. 
How would I do it 'properly',  do I have to use the recursive every time?
Cheers,  D
