Running into another issue. So i'm detaching my object and passing it
along in a session.
I'm now getting this error WARNING:
javax.jdo.JDODetachedFieldAccessException: You have just attempted to
access field "contactInfo" yet this field was not detached when you
detached the object. Either dont access this field, or detach it when
detaching the object.
my contactInfo is an embedded persistent object in the object i am
detaching.
@Embedded
@Persistent
private ContactInfo contactInfo;
If i make contactInfo @Persistent(defaultFetchGroup="true") then i get
this error.
WARNING: The datastore does not support joins and therefore cannot
honor requests to place child objects in the default fetch group. The
field will be fetched lazily on first access. You can modify this
warning by setting the datanucleus.appengine.ignorableMetaDataBehavior
property in your config. A value of NONE will silence the warning. A
value of ERROR will turn the warning into an exception.
What is the correct way of making sure this embedded object is also
detached when i save it to the session?
