Issues #2964

[trasher]

Hello,

Thanks for the PR, I got some remarks. First, CS checks are failing (not very important, but this needs to be fixed).

Second, copying the entire showNavigationHeader is probably not the way to go; we need to find something more generic I guess.

Maybe adding an option to existing method should does the trick (I've just took a very quick look)

[trasher]

Great; that sounds better :)

Just one more remark: maybe this new code should be run only if we're from a Ticket (or maybe from a CommonITILObject; I guess this should appply as well on Changes and Problems).

[Drimmwald]

I think you are right. Now code working with Changes and Problems, but some styles of these statuses are absent. I will try fix in the near time.

Sorry to answer late on this submission, but this is not ok imo.
We have an existing iconography for ITIL status representation and the submitted colors didn't match at all.

This set may be outdated and subject to review but we need to do a spec on this (on spec wiki: https://github.com/glpi-project/spec/wiki).
And this change should aim next major version.

In parallel, we can try to transform theses images in full css.
