Hi Everyone,
I just upgrade to 2.10.4 and found error message when using filed
list:reference.
APP : welcome
DB
db.define_table('parent', Field('name'))
db.define_table('student', Field('name'), Field('parent', 'list:reference
parent'))
in APPADMIN
- from parent table insert : father, mother
- from student table insert : student1 with select father (or mother or
both)
- open student grid view : return error
<type 'exceptions.TypeError'> isinstance() arg 2 must be a class, type, or
