[web2py] SQLFORM.grid not doing what I expect

[Mike Veltman]

Gentle people,

I have the following grid:
query = ( (db.lvdisksetup.lvgroupname_id == usedlvdisksetup) & 
(db.lvgroupname.id == usedlvdisksetup) & (db.lvdisksetup.lvdisk_id == 
db.lvdisk.id) )
    fields = [db.lvdisksetup.id, db.lvgroupname.lvgroupnamedesc , 
db.lvdisk.lvdiskdesc, db.lvdisksetup.lunid]

    form = SQLFORM.grid(query,
        fields=fields,
        orderby=['lvdisksetup.lunid'],
        csv=False,
        create = False,
        maxtextlength=45
        )

I want to manipulate db.lvdisksetup but in stead it manipulates 
db.lvdisk :-)

What causes havoc by deleting essential table data :)
