Thanks to @redclov3r for the report and the analysis.
DoctrineEntityHydrationExtension::dehydrate()returns the entity identifier as-is. For an entity whose id is a Symfony Uid (e.g. withUuidType) that is aUuidobject. For a#[LiveProp] arrayof entities,LiveComponentHydratorthen runsisValueValidDehydratedValue()on the result, which only accepts scalars and arrays, and throws "Unable to dehydrate value of type array".The extension now casts
AbstractUididentifier values to strings (this also covers composite ids). Integer/string ids are unchanged, and the string is accepted byEntityManager::find()withUuidType, so hydration works unchanged.Tests: a new Uuid-id entity fixture, an extension round-trip test, and a
LiveComponentHydratorTestcase with an array of such entities. Both fail without the fix (Uuid object returned /LogicException) and pass with it. No CHANGELOG entry, as recent bugfix PRs add none.Replaces #4131, which got closed when my fork was accidentally detached.
