GenericTabularInline broken as of r13708

[Sean Brant]

Using GenericTabularLine seem to have a regression as of r13708. I get the following 'NoneType' object has no attribute 'user' using r13708 and no error using r13707. Line 292 of options.py is throwing the error return request.user.has_perm(opts.app_label + '.' + opts.get_add_permission()) because request is None. Sorry I don't have a patch Im not real clear on what is going on in the code. As a side note im just using a barebones GenericTabularLine and ModelAdmin.

[Gregor Müllegger]

Seems to me like r13708 introduced this error. But it's not obvious why yet. I will look into in detail later.

[Gregor Müllegger]

Adding test suite and fix for the issue.

[Gregor Müllegger]

Sorry for my previous embarrassing comment. I should have read the title of the ticket and looked at the specific revision in more detail.

However it's fixed now. Fix and tests are attached in the patch.

[Jannis Leidel]

(In [14555]) Fixed #14670 -- Made GenericTabularInline aware of changes made in r13708. Thanks, gregmuellegger.
