Not in EOModeler, but you can do it in the awakeFromInsertion
method of the EOEnterpriseObjects. That is the proper way to do
this.
It would be... if a failed ec.saveChanges wouldn't re-insert
deleted objects into the EC, leading to a call to
awakeFromInsertion() all over again. As an additional measure, you
should factor out this code into a "protected void initialize()"
and only call it from awakeFromInsertion when the GID is not a
temporary one (David Teran's idea, never tested it but it sounds
like it should work).
What sort of failed saveChanges()? I've seen this when a delete
rule was set to deny or validateForDeletion threw. In those cases
the EC state is totally trashed.
It might well have been a cascading delete, but I don't really remember.
That the state is "totally thrashed" is a bug of it's own, though.
What's the bug number?:)

Is there any way to set up a default values in EOModeler?
No.
Sure there is: use ERXGenericRecord in Project Wonder, which has
support for a "default" userInfo key (supporting timestamps,
relationships and so on
Well, yes, if you use Project Wonder there is always something that
will do it. :-)
Kids, listen to the man :) He sure got it right.
Actually, my implementation is a loose rewrite of something I've seen
a few years ago from some dutch site. I found it to be to good an
idea to let it pass. And it wasn't very hard to do. AFAIR, I wrote it
on the train to the Wocoa in Lausanne.
But "Out of the box" EOF has no facility for this. There are many,
many useful things that can be done with the userInfo dictionary.
Yup. Like ERXValidation for example, a light-weight version of
Validity, without the fancy editor stuff.
Cheers, Anjo
