There are a couple spots where it still says 'Drupal 7.'

Forgot to set to 'needs work.'

Also: #1861598: Examples for Drupal 8 needs relatively stable feature set

Created a patch that fixes the failing simpletests, this will unblock testing of other patches against the 8.x branch.

Included patch from #7 (by marvil07).

Still needs a lot of changes to be a proper Drupal 8 example.

Changing status to allow the testbot to pick it up.

It seems @marvil07 is not working on this issue so I will try to finish it. If I'm wrong just let me know ;)

@rteijeiro you might also want to look at https://drupal.org/node/2074243

Just want to be sure and reference #2074243: Convert DBTNG to OOP from here.

Change origin issue to point at d8 port for examples issue inside this module queue

Feel free to assign yourself back if you're still working on it.

Fixed routing, removed hook_menu(), updated form and controller base classes.

Fixes to hook_help().

Did they change it again?? :-)

I'm not sure about this, because of https://drupal.org/node/2250345

The example code there uses Request.

Also, I just applied this patch and after installing the module I get this error: Recoverable fatal error: Argument 2 passed to dbtng_example_help() must be of the type array, object given in dbtng_example_help() (line 68 of modules/examples/dbtng_example/dbtng_example.module).

Kind of a mystery to me how it passed the test.

Here it is with the Request object.

19: 1868178_19.patch queued for re-testing.

And we're calling that fixed.

Thanks, folks!
