This pull request attempts to fix an issue where the incorrect blueprint is resolved on localisations, where the collection is dated andhide: true is set on the entry blueprint.

I'm not sure that this is the final fix, but it certainly fixes it on the sites I've tested it on.

Related to support ticket#7046.

Steps to reproduce

1. Setup a multisite, with two sites: site A & site B.
2. Create a dated collection, setup in both sites.
3. Configure two blueprints for the collection:
   • home (should be hidden)
   • landing_pages
4. Create an entry in site A
   • It should use the home blueprint:blueprint: home
5. Localise the entry into site B
6. Then, run the following code snippet in Tinkerwell:

   useStatamic\Facades\Entry;useStatamic\Facades\Stache;Stache::clear();$entry = Entry::find('id-of-the-localized-entry');$entry->blueprint()->handle();

   • We expecthome to be returned, because we're explicitly setting the blueprint on the origin entry.
   • However,landing_pages will be returned instead.
     • This is because it's failing to resolve the origin entry, so it's falling back to the "default" blueprint, which in our case happens to belanding_pages since thehome blueprint is hidden.
       • Because its a dated collection, whenBasicStore@getItem callsEntry@ getCurrentDirtyStateAttributes(), it attempts to get the entry date, which ends up calling theblueprint() method.
       • However, at this point, it's possible the origin entry hasn't been loaded into the Stache yet, so it doesn't know about the origin blueprint, so it caches the "default" blueprint.
       • This cached, default blueprint, is what ends up breaking things. This PR fixes it by clearing the blueprint cache key inEntry@hasDate.

TLDR:

• Needs to be a multisite, with at least 2 sites.
• Collection has to be dated.
• Collection has to have two blueprints: one hidden, one not.
• Entry needs to be localised into another site.
• Origin entry should be explicitly using the hidden blueprint.
• Need to runphp artisan cache:clear before attempting to get the localization's blueprint.
