Does your project intend to support complex relations?

I'll give you an example:

I have a model called Resource which has a foreign key on field project (for model Project)
The Project model also has a foreign key on field organization (for model Organization)

Therefore, one Organization can have many Projects and each Project can have many Resources.

In the ResourceReport (model = Resource) I have the following fields:

fields = [
'title', # --> title field belongs to the Resource
'type', # --> type field belongs to the Resource
'project__title', # --> title field belongs to the Project associated with the Resource
'project__organization__name', # --> name field belongs to the Organization which is associated with the Project associated with the Resource
]

Grouping works fine by using this config:

list_group_by = (
'project__organization__name',
'project__title',
'type',
)

However, filtering does not, even though the config should basically be the same:

list_filter = (
'project__organization__name',
'project__title',
'type',
)

The report renders 2 select fields with different ids and names (project__title and project__organization__name) but the options are the same in the two select fields (both of them have been populated with project__title values). Also the labels are the same (the label that should be used for the project__title select is used for both select fields).

Should your project work for this case and this is a bug or you didn't cover this kind of relations when you designed it?
