Subject Re: Firebird support
Date Sat, 08 Jun 2013 15:53:19 GMT
I actually have a working firebird adapter at least as of cayenne 3.1.  It
was targeted at older firebird -- version 1.5.  But it should be a good
starting place; it was based off the previous one in cayenne.  We're not
using it anymore.  I can send you a link on Monday.
