There is a patch that was discussed just the other day, which I think does what you are looking for:

https://issues.apache.org/cayenne/browse/CAY-560

Also in 3.0, there is a new type of query, EJBQL query that allows multiple joins.

Hello everyone,

I would like to express multiple joins via Expressions.

I found someone had the same problem back in 2005

http://objectstyle.org/cayenne/lists/cayenne-user/2005/10/0032.html

but could not find further reference to the solution Andrus drafted in the replies.

I am using cayenne 1.2.3 now - is there anything available in the current releases that implements multiple joins for Expressions?

thank you

regards

Tobias
