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:
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.
