    Hi!

    I got an "Error generating classes" when trying to generate java-classes
    for one of our EOModel. I'm on osx 10.2 (6C115) and WO5.1.4

    I got this message on a EOModel that has been converted from an WO4.5
    application.

    When generating java-files on a EOModel made with WO5.1 I don't get any
    errormessages.

    I fetched woproject from cvs (today) and copied woproject/lib/cayenne.jar
    to /Library/Java/Extensions

    If anyone think this might be a bug they want to look into, I can email
    them the EOModel directly.

    bash-2.05a$ cat eo.xml

    <project name="kajhp" default="doit" basedir=".">

    <taskdef name="wogen" classname="org.objectstyle.woproject.ant.WOGenerator">
         <classpath />
    </taskdef>
    <target name="doit">

    <wogen map="faq.eomodeld" destDir="eo" usepkgpath="false"/>

    </target>

    </project>

    bash-2.05a$ ant -buildfile eo.xml -verbose
