What is the relation between ADF faces and Trinidad?

Question

I was looking into the documentation of ADF Faces TreeMap component and got a little bit surprised by the namespace of the event called AttributeChangeEvent that this partcular component supports ie org.apache.myfaces.trinidad.event.AttributeChangeEvent . What exactly is the relation between ADF Faces and Trinidad ? Is one the super set of another ? What exactly is the history behind these namespaces ?

Answer 1

Apache Trinidad used to be ADF 10g. Oracle gave ADF to the Apache foundation (minus some stuff) and started work on ADF 11g. As such, Oracle 11g depends on a lot of the core libraries that are now maintained by the Apache foundation.

In fact, the afh: namespace is often used as trh: since it's now properly in the Trindad libraries.
