Hi,
I just got this going a few days ago for the first time - using
ubuntu too (which I'd only loaded on for the first time a few weeks
ago - and is my first debian-esque linux install).
Anywho, the way I went about it was to:
0. Install Java (I installed jdk 1.5 aka 5)
1. Install Eclipse
It is indirect. Access to all EO values is via storedValueForKey.
This then eventually calls willReadRelationship, but willRead is
called first. Same for willChange().
EOCustomObject subclasses might be different. Does anyone still use
them?

Hi,
You could use EOUtilities.createAndInsertInstance to create the objects and
insert them immediatly in the EDC. Note that you should never modify objects
that are not inserted in an EDC, so you should always insert them as soon as
possible.

Hi, Frederic,
I agree with all who are recommending "the WO way" of inserting your

As Alan pointed out, you could revert the editing context. Other
options are to just dispose that EC, or use the undo manager to undo
any changes.
Trust us - this is the right approach.

Frederic,
I'm not sure what you mean by over-complicated. Whenever you create
an EO, you need to insert it into the editing context - you should do
this immediately when the object is created.
You can then perform a save changes at any time, and it will
serialize all outstanding changes
