Collections not shown in Twig

[milosa]

Collections are not printed in the Twig templates.

When trying this example, the loop doesn't print anything.

Also, I noticed that when I print features|length in twig, I get some weird numbers.
I added 1 feature in the back end, so I’d expect it to print 1. But instead I got 4.
When I add another one, it should be 2, or maybe 8, but I got 11.

Even though features has elements (because it's length > 0), the stuff inside the loop doesn’t get executed.

Maybe it's related to #1438 or the fact that htmllang() is still empty and therefore the system doesn't know which translation to use (#1437)

hey @milosa the PR I mentioned above should resolve the |length issue. This should resolve it, if not let me know :-)

[milosa]

@I-Valchev The length is now correct. The for loop still doesn't print anything though.

I'm not sure if you're aware, but for me, the htmllang() is still empty. #1439
I have a feeling this might be related to this issue somehow.

@bobdenotter #1455 only fixes the |length part of this issue, right?

[bobdenotter]

Re-opened.

I'm having the same problem with imagelist.

It works fine when retrieving the first image in a template e.g. {{ apartment | image | thumbnail(320, 240) }}

However, when I try to loop through the imagelist to display each image, the for loop does not seem to run. It seems as though the imagelist is empty.

I've updated the docs for this: bolt/docs#1048

PR with code changes to follow shortly.

@benplummer Latest commit to #1485 also fixes it for Imagelists.
