Hi Ikai,
Thanks for your reply. Anyway, the problem is a bit deeper. When I set
the property to null, my App Engine Data Vievwer panel was fixed. So
null is valid value for my field. Before that, I accessed the field
programically (JAVA through JDO) and get very strange value for that
field:
com.google.appengine.api.datastore.PostalAddress@0 <- zero is probably
bad value here.
I suppose that it was a bug in JDO when persisting the entity do
DataStore. After fixing property (setting it to null), it seems to
work.
