Closure metadata doesn't work with doctrine/persistence 2.2

[hlecorche]

Since doctrine/persistence 2.2.0, the Gedmo\Tree\Strategy\ORM\Closure::processMetadataLoad method does not work anymore :

• associations are not created
• indexes are not created

Tested with Symfony and doctrine-extensions 3.1.0 :

• Works in a dev environment. But not in a production environment
• Works only with doctrine/persistence < 2.2.0

doctrine-extensions issue or Symfony issue ?

I think there is a link with #2236

Thanks for reporting! Sorry, it has been a while since it was reported.

Since there are some problems with this, we decided that it's better if the user adds the ancestor and descendant mappings manually: https://github.com/doctrine-extensions/DoctrineExtensions/blob/13dd920b1c6a5f29f92aef383f68e40913431c6a/doc/tree.md#closure-table

I'm closing this issue, but feel free to re-open if that doesn't fix your issue.
