Titles in a user's activity tab displays as just text and not a link.

Replicated issue locally. Submitting proposed patch to fix this issue.

Reproduced on a fresh install, it looks like we are lacking test coverage here, tagging.

Unassigning, based on the other issues created by @japo32 I don't think they intended to work on the patches. Please correct me if I'm wrong!

Because this needs tests setting to needs work.

Also setting the correct parent relationship.

Ahem.

In previous patch l function is directly, but now l function is used with drupal static class as core changes.
Reroll patch, thanks Cottser for mentoring.

Still needs tests. Also it seems that the link to new comments is also affected by the same problem.

Granted that cell data takes render arrays, wouldn't it be appropriate to supply a proper '#type' => 'link' element instead of #markup?

Here is the patch which remove title and replies section.

Yeah i agree with you that we should use '#type' => 'link' element instead of #markup?, if we implement this then we have to change in many places and that's not a feasible way.

Using #markup is not the right fix.

This just hides the problem ...

The string needs to come from a function that creates safe markup.

Also \Drupal::l is deprecated, so using #type => link is what should happen here.

Here is the patch according to suggestions from @Fabianx in #12. Will work with tests soon.

Invoking tests.

Here is what it looks like with patch applied:

So I was just looking at this ticket https://www.drupal.org/node/2309737 which asks to remove direct format_plural calls with function from the translation object: IE:
\Drupal::translation()->formatPlural()

So this patch will need to be updated so that it doesn't conflict with the other patch.

Thanks @jaimekristene for pointing this out. Here is the corrected patch. Can anyone help me with tests. I guess I have to write simpletests for this since we will carry out tests in a virtual instance.

There are tracker_test_views.info.yml and views.view.test_tracker_user_uid.yml, but I think they are for views.

Patch with tests added.

Applied the patch and verified manually that it is working. Also executed the test from #20 locally without the rest of the patch and the new assertions fail, which shows that they are working as intended.

RTBC + 1 - looks great

This issue is a normal bug fix, and doesn't include any disruptive changes, so it is allowed per https://www.drupal.org/core/beta-changes. Committed 390315b and pushed to 8.0.x. Thanks!
