Bug Report

Versions < 4.0.0 are more than likely also impacted by this bug.

Summary

Hello, I am the developer of DoctrineDiagramBundle. With this bundle I can generate class diagrams from my Doctrine entities.
The problem is that when an entity has a Enum type property my bundle fails and throws a Fatal error.

After some hours of research I identified the problem: some methods in \Doctrine\Persistence\Reflection\EnumReflectionProperty don't work properly and generate a fatal error.
More precisely, any inherited method in EnumReflectionProperty will generate an error.

Internal error: Failed to retrieve the reflection object

Current behavior

Methods defined in EnumReflectionProperty work as expected, for example:

• \Doctrine\Persistence\Reflection\EnumReflectionProperty::getName Ok
• \Doctrine\Persistence\Reflection\EnumReflectionProperty::isPrivate Ok

But methods inherited from parent will fail, for example:

• \Doctrine\Persistence\Reflection\EnumReflectionProperty::hasDefaultValue Fatal error
• \Doctrine\Persistence\Reflection\EnumReflectionProperty::isPublic Fatal error

Expected behavior

All methods from EnumReflectionProperty must work properly without any error.

How to reproduce

To reproduce the issue simply call any inherited method in EnumReflectionProperty.

I reproduced the issue installing and using DoctrineDiagramBundle:

• Install jawira/doctrine-diagram-bundle.
• Create an entity with an Enum type property, this property must also be a Doctrine property. This is described in the original issue:
  Property::generateVisibility() chashes if property is an EnumReflectionProperty jawira/entity-draw#17.
• Execute bin/console doctrine:diagram:class and voila, you get Fatal error.

Solution

As per documentation, when a Reflection class is extended and constructor overwritten, then the parent's constructor must also be called.
