Example :

• We have 2 content types A and B
• B extends A
• A defines an attribute of type content.
• In this attribute, the referenced content type is B

Here is the parsing behavior:

• A is parsed before B
• The content attribute defined in A is parsed
• We check that the refernced content type (B) exists => KO. It does not exist because it will be parsed after A.

Solution:

Like before the CMS-9613, check the attributes of type content in ContentType.postInitialize() method
