Subject Re: Cayenne Modeler - Local DataSources
Date Mon, 29 Mar 2010 16:43:21 GMT
You are probably running into a known issue CM has with HypersonicSQL
(the embedded database Cayenne uses to save preferences -- an "eat
your own dogfood" kind of thing).  Unfortunately, the simplest thing
to do is delete the preferences DB and start over.  If you look in
your ~/.cayenne/prefs/1.2 directory, you'll probably see multiple DB
files instead of just one and somehow HSQL is using the wrong one.  If
you are on a Mac and use Time Machine, it is possible to go back and
find a working DB and restore it, but still painful.

Cayenne 3.1 is scrapping HSQL, but that probably doesn't help you ...

 I am using Cayenne Modeler to manage the datasource design.  Unfortunately when I move
from one project to another the Preferences do not seem to maintain integrity.

DataSources be maintained separately from the project and CM might be doing this, however
when I add a new datasource, and save it, it reverts back to the old set of datasources.
