    Thanks Andrus,

    I am going to try and help you guys out again. It has been over a year
    since I contributed anything. Any way, I am currently working on the
    EOModel import routine. I found some issues with it, and I just about have
    a patch to fix those items. I will open up a Jira issue once I get done.

    I really am interested in making EOModels work instead of Cayenne.xml,
    because I want to use WOBuilder and have the key completion work with
    EOGenericRecords. I will be building a WOCompatibility framework to address
    those needs. So if anyone has any ideas about what I should add please let
    me know.
     
    Thanks
    Garry
