Currently only make AssetReference as array is working.

When I can get the fix? I really hope I can get the fix very soon before 1.0 release.

 

@optimise While we wait for an actual release of this fix, we have posted some workarounds that make this work without problems. You can see them here https://forum.unity.com/threads/assetreferencedrawer-does-not-dirty-the-serialziedproperty.568894/
