Add breadcrumb in template

[Mondane]

I'm customizing the error template and want to add display a breadcrumb. Let's say for the 404-page, it should be:

Home > 404 page.

Is it possible to call your bundle in a template to add objects to the trail, if so, could you give an example?

[Abhoryo]

You can try with the globals variables of twig:

#app/config/config.yml
twig:
    globals:
        breadcrumb_trail: "@apy_breadcrumb_trail"

After that you can call the service inside twig template.

{% app.breadcrumb_trail.add('404 page') %}

Doing so ends up with this message:

Whoops, looks like something went wrong.

1/1HttpException:

Is the naming incorrect?

Do you have more informations about the error because what you show me isn't very useful.
I'll try tonight and if this dosen't work, i'll create a new twig function to do so.

Ok the following code works for me:

{% do breadcrumb_trail.add('404') %}

Thanks, that works great!

I've add some doc about this. Thanks for the idea.
