Property Accessor called with default value of property since 3.18.0

Properties that have an Accessor setter, are called with the default property value whenever that class is deserialized

This is a BC break since 3.17.1. It happens since 3.18.0, specifically PR #1417

Steps required to reproduce the problem

1. Take an example class with both traditional and promoted properties, some with accessors:

   class DefaultValuesAndAccessors
   {
   public string $traditional = 'default';
   #[Accessor(setter: 'setTraditionalWithSetter')]
   public string $traditionalWithSetter = 'default';
   
   public function __construct(
       public string $promoted = 'default',
       #[Accessor(setter: 'setPromotedWithSetter')]
       public string $promotedWithSetter = 'default',
   ) {
   }
   
   public function setTraditionalWithSetter(string $value): void
   {
       $this->traditionalWithSetter = $value . '_fromsetter';
   }
   
   public function setPromotedWithSetter(string $value): void
   {
       $this->promotedWithSetter = $value . '_fromsetter';
   }
   }

2. Deserialize some data into the class: $serializer->fromArray([], DefaultValuesAndAccessors::class)

Expected Result

{
    "traditional": "default",
    "traditionalWithSetter": "default",
    "promoted": "default",
    "promotedWithSetter": "default"
}

Actual Result

output in 3.17.1:

{
    "traditional": "default",
    "traditionalWithSetter": "default"
}

output in 3.18.0:

{
    "traditional": "default",
    "traditionalWithSetter": "default_fromsetter",
    "promoted": "default",
    "promotedWithSetter": "default_fromsetter"
}

Hi @annervisser ,

Thank for the report.

Would you be able to check if the pull request fixes your issue?

Thanks!

[annervisser]

Yes, that PR should fix the issue :+1: Thanks for the effort of putting my test case in as actual test :smile:

[eerison]

as I can see the PR was already merged, is it missing something else here?

[annervisser]

This should be fixed now in version https://github.com/schmittjoh/serializer/releases/tag/3.23.0 .

[eerison]

I'm still facing the same issue in release 3.23.0 :/

is it working for you on that version @annervisser ?

@annervisser do you mind to reopen this issue, I'm facing the same issue in 3.23.0

Edit: Sorry, I was just looking for the new fields that as added

{
    "traditional": "default",
    "traditionalWithSetter": "default",
+    "promoted": "default",
+    "promotedWithSetter": "default"
}

But I just realised that, the issue is because there is the suffix _fromsetter. and Yeah, in the last version it's as expected

{
    "traditional": "default",
    "traditionalWithSetter": "default",
    "promoted": "default",
    "promotedWithSetter": "default"
}

Then, it's working ✅ :)

We were still facing an issue with 3.23.0, so we're still running 3.17.1. Something to do with deserializationHandlers, we'll research this later & submit a proper issue.

But glad to hear it's fixed for you @eerison

Yep, This issue was "fixed" (But we have a different output.)

But I'm also facing others issues
