[PythonReports-users] Adding a Field to Detail band

[Werner F. B. <wer...@fr...>]

When I do:

1. Click on "New Template"
2. create "data"

 >>> data = ds.query(db.Cellarbook).all()
 >>> data
[Cellarbook(storagelocation=None), Cellarbook(storagelocation=None), 
Cellarbook(storagelocation=None), Cellarbook(storagelocation=None), 
Cellarbook(storagelocation=None), Cellarbook(storagelocation=None), 
Cellarbook(storagelocation=None), Cellarbook(storagelocation=None), 
Cellarbook(storagelocation=None)]

3. Click on "New Field"
4. Click within "Detail" band I get this exception:

wx._core.PyAssertionError: C++ assertion "Assert failure" failed at

Any hints on what I am doing wrong?
