Really curious...
Changing the line
@Bean(converter=ParentBeanConverterImpl.class) protected
JetspeedFolder parentFolder;
to
@Bean(converter=ParentBeanConverterImpl.class) protected
JetspeedCMSObject parentFolder;
Worked well because all parent objects will be of type
JetspeedCMSObject. This is not really what I want but I have to move on
and later set constraints...
But as I said. I'm still curious. Why second time trying loading worked?
