Unfortunately it seems to be a web2py grid/smartgrid bug. I opened a ticket
here: http://code.google.com/p/web2py/issues/detail?id=1851
Meanwhile please note that defining an old style virtual field does not
break the smartgrid:
class MyVirtualFields(object):
def testfield(self):
return 'foo'
db.testtable.virtualfields.append(MyVirtualFields())
I'll make a few updates to web2py with this occasion :)
Thanks,
