I'm trying to store a list of ContactEntrys in the appengine
datastore. When I persist the group, I get the following error. Is
there anyway to get around this?
Thanks,
HTTP ERROR: 500
contacts: com.google.gdata.data.contacts.ContactEntry is not a
supported property type.
RequestURI=/update
Caused by:
java.lang.IllegalArgumentException: contacts:
