I'd say that would be cache related, as Cayenne is caching the data
from the database, switch the cache of in the Modeler perhaps and that
should fix your problem.

There are a few ways of doing it. My favorite is to use SelectQuery's with
caching enabled, and OSCache as a cache provider:

Then you assign each query a cache group String, and configure expiration
policies for each cache group. Finally t
You are welcome. Certainly keep asking questions if you have more :-)

Hi Richard,
To avoid copy/pasting, you can probably start 2 Cayenne stacks. If you are on
Cayenne 3.0, this will be 2 Configuration objects and you can add a correct
DataNode via API to each stack.
In 3.1 it is a bit more elegant. In 3.1M2 2 stac
Synchronizing on a DataObject is not going to help across contexts as each
context has its owen copy of an object. But you can create your own arbitrary
lock object of course that is shared between all threads. If this has to be

OK. Got it! I removed the SQLResult and than cast the Objects to DataRow:
String sql = "SELECT a.author_id X, count(*) CNT FROM
`publication_authors` a WHERE a.`cid` != 0 and a.cid = 1234 group by
a.author_id ORDER BY a.`cid` ASC";
SQLTemplate query = new

Ah got it, the exception is in your code, not the Cayenne code.
Your SQLResult defines the result as Object[], so this is what you are getting
here. You can either keep casting to Map and remove the SQLResult code. Or keep
using SQLResult and cast to Object[]

What are you all using for your JSON library with cayenne? I am looking for
some feedback on what works well out of the box or with little work. I can't
seem to find a good JSON library that works well with cayenne and db2 on an
as400. My initial research pointed me to GSON (Google JSON library)
