I'd like to second this suggestion. There have been several instances that I've
made required fields nullable solely because validation occurs prior to the
@PrePersist lifecycle callback.

I'm looking for some ROP expertise here... can someone provide a simple example
of how to run an ROP server instance outside of running the Cayenne Maven task
that does the same? Any help is much appreciated.

The way I have it working is by using a custom sequence for PK generation. In
the dialog to set it up you can choose the "cached PK size" which determines
how many PKs cayenne will grab at a time for a given transaction. If you set it
to 1 it will only grab one at a time, but keep in mind that t
I can't speak to what Cayenne is able to do solely when using an ObjectQuery,
but from a database perspective it sounds like you want to be using a view that
provides the date-only version of your datetime column. Then you could query it
just like a table and do your sort on the date-only column
client, or the server as well?

Have any of you ever had to tackle the problem of obfuscating a project that
uses Cayenne? I'm looking to find a way to be able to obfuscate a Cayenne ROP
project and I'm hoping that we're not the first to attempt this.
Our thinking is that we would write a utility/maven plugin to obfuscate the

I have sets of tables that contain versioned data; one table acts as the parent
and the other contains the revisions of the parent. The parent record stores a
long PK and a string ID. The revisions table stores a long PK, the long PK of
the parent (with FK relationship), a replacement date (if n

I'm seeing the following NPE on the client when connecting my ROP client after
upgrading from 4.0.M2 to M3:

You should be able to catch the 401 error on the client end and do something
useful with it.
Does that help?

I don't think you need to prompt the user if you keep the user's authentication
details in memory.
I have a rich client application that uses the Apache Cayenne Remote Object
Persistence framework to access and store data. Thus far I have been unable to
find a graceful way of detecting and handling a client connection timeout. A
