[web2py] manipulating dal.field.attrib

[yashar]

i used this:

db.define_table('test',
    Field('service_type'))

def form1():
    db.test.service_type.requires=IS_IN_SET(['Trial'])
    form = SQLFORM(db.test)
    if form.process().accepted:
        pass
    return dict(form=form)
    
def form2():
    db.test.service_type.requires=IS_IN_SET(['one month','one year'])
    form = SQLFORM(db.test)
    if form.process().accepted:
        pass
    return dict(form=form)

but this is not working, when you open form1 and then form2 and then submit 
form1 it is not saving any data.

so db.test.service_type.requires=IS_IN_SET(['one month','one year']) is not 
creating an instance for this form but setting that requires for all forms, 
how to solve it?
