[web2py] represented fields and jqgrid

[niknok]

I .represent a field as follows:

        db.auth_user.gender.represent=lambda i: db.aux_gender[i].concept[:1] if 
i>0 else '?'
        db.auth_user.member_status.represent=lambda i: 
config.member_status.get(i)[:1] or '?'


The first one works, and displays data in jqgrid as expected:'M','F'
or'?'. The second only shows a blank cell in jqgrid.

I tried a DAL select query and crud.search and the data is represented
correctly.
