You both are righ:
What's work now (also should worke before):
selectable=[('change price 100', lambda ids: modify_price(ids,100) ), ]
and the function in the same controller:
def modify_price(ids,inc):
print request.vars.records
print ids
print inc
Both request.vars.records and ids are lists also with only one selected
Thanks for help
