ORA-04055

Error: ORA-04055: Aborted: "string" formed a non-REF mutually-dependent cycle with "string".

Causa: This compilation was aborted because the library unit that was compiled would have formed a non-REF mutually-dependent cycle with some other library units. This happens when an attempt is made to compile types that have attributes of other types that may participate in a cycle with this type. Example:

Acción: Break the cycle (possibly by adding a REF or by using another type).
