[JIRA] Commented: (CAY-943) Support multiple cayenne.xml files in the project

-------------------------------------

Another related issue - the ability to redefine entity listeners (and callbacks?) per project. Often it makes sense to define entity mapping in a common "library" project shared by many applications, but defer listener definitions to individual applications. This way the listeners can have application-specific logic. Currently this is possible to achieve via API, but  ideally this should be done via mapping. What this means is the ability to merge two obj-entity definitions into one.

> A few years ago when we raised this issue, the idea was to create a special DataMap-only project. Currently I am more in favor of a runtime merge approach that can take multiple cayenne.xml files in runtime and merge them into appropriate domains. The details to be hashed out ....
