[5.x]: Only first entry in index shows thumbnail

[gregorterrill]

What happened?

Description

In all of my entry indexes, only the first item in the list is showing the preview thumbnail next to the title:

However, if I add the column for the asset field set to "Use for element thumbnails", it shows correctly in that column AND all of the preview thumbnails start working too:

Removing that column again reverts it to the first screenshot, where only the first item has a thumbnail.

This is the case in multiple sections with different entry types, and it's not specific to particular entries (e.g. if I enter a search term so that "Winterlude" is the first item in the list, it shows its thumbnail while any subsequent entries do not, even though in the unfiltered view it did not show its thumnbail).

To be clear, your “Representative Image” field is set to “Use for element thumbnails” from the field layout designer, correct?

Assuming that’s the case, unfortunately I can’t reproduce. Can you send a database backup and your Composer files into [email protected] and point us to the section where this issue is occurring?

Yep, it is. Sent in the backup and files via email yesterday. I also just realized the same thing is happening in Matrix fields within entries, where the included entry blocks also have an asset field set to "Use for element thumbnails". Here, both of these have an asset set in the thumbnail field, but only the first in the list shows it. If I reorder the items, save and reload, then "Another Business" shows its thumbnail while "Whatever Inc" does not.

Also if I double click the item in the second position, and resave it in the slideout, then the thumbnail appears in the second card - until I reload the page, and then it's gone again.

Thanks for sending those in. Tracked it down to the where field handle in your “Event (Internal)” entry type, which is conflicting with the $where property on the element query, resulting in this bug.

If you rename that to something else, all thumbnails will load. I’ve gone ahead and made where a reserved field handle for the next release.

Renaming that field did the trick! Appreciate you tracking that down.
