Sorry, wrong jar URL. Here is the right one:

Hi Tobias,
This was fixed on trunk recently (you probably got the Jira email
already). The fix didn't make it to the upcoming M6, but will be
included in the following releases. For now your option is to build
the trunk yourself or get the Modeler from Hudson CI:
http://hudson.zones.apache.org/hudson/view/Cayenne/job/Cayenne-trunk/lastBuild/org.apache.cayenne$cayenne-modeler/
The later option requires a bit of magic. cayenne-modeler-java-3.0-
SNAPSHOT.jar is a jar of a jar. So it needs to be unpacked, and
inside you'll see runnable CayenneModeler.jar.

I just tried to track down the error and started with a simple two

I was not able to recreate the issues this way.
I then got back to my production schema/mapping and tried to
simplify the
schema to see where it breaks.
It turns out that the error occurs even without a change to the
database
schema.
So with the complete cayenne map, reverse engineering the same
database
schema gives me the "No error message" popup.
I started from scratch yesterday reverse engineered the database
and added
the custom mappings with the modeler. So some of my custom mapping
must
cause this error.
this is the same in 1.2 and 3.
I am a bit anxious posting the production schema/mapping here in
the mailing
list. Would someone look at it if I did?
thanks

Thanks! We'll take a look at it.
In general, is there an overview to see the differences of the 3
versions
1.x, 2.x and 3.x?
2.0.x is exactly the same as corresponding 1.2.x, only with
package names
changed from org.objectstyle to org.apache. 2.0.x is great for
migration
from the ObjectStyle releases as it does not introduce any new
functionality.
3.0, while still in development is being used in production by many
companies already. We are trying to wrap up the final release
soon, but
there are still a few things to finish. Here is a fairly complete
overview
of 3.0 new features already available:
http://cayenne.apache.org/doc/guide-to-30-features.html
The list is pretty long and it has a lot of great things (useable
query
caching, leak free DataContext, greatly enhanced Modeler, lifecycle
callbacks, more supported attribute types, including Java 5
enums, etc.,
etc.)

I just downloaded 3.0. Started up the Modeler and did the same
remove /
reengineer / skip existing operation and I got the same empty

as with 1.2.

Hi Tobias,
This looks like a bug to me. Probably worth opening a bug
report, but
the
easiest thing would be to upgrade to Cayenne 3.0 for instance.
Chances
are
this problem is fixed there already.

Hi,

I have updated a portion of the schema in the database. I
delete the
DbEntities and ObjEntities of the tables that were changed.
I then click reverse Engineer from database. I get popups asking
whether
to
overwrite existing Objects. I click "remember my decision" and
NO.
at the end I get an error popup without a message. It is just
containing
the
red error icon and a title reading "Error Reengineering
Database".
This error does occur also when I select not to remember my
decision
and
click through each popup one by one.
When reverse engineering the whole database, removing all
ObjEntities
and
all DBEntities, before reverse engineering the error does not
occur. I
have
many custom mappings redoing the existing mapping is not
really an
option.
Any help highly appreciated.
thanks,Tobias
