Hi GAE team,
Any workarounds for this issue?
Thanks

The problem is still not solved.
Although you can "persist" an object with multiple relations of the
same type. When you actually query the object, the retrieved object
has duplicates for the multiple relations.
As in, if I were to persist instances A, B inside C. When I query for
C, both objects retrieved will be A. There will be no B.
This is a serious bug!

Michael,
In your jdoconfig.xml file add this entry:
<property
name="datanucleus.appengine.allowMultipleRelationsOfSameType"
value="true"/>
Thanks

Hi all,
I am also experiencing this problem on GAE 1.3.0.
Using multipleRelationsOfSameTypeAreErrors helps not in all cases,
when I am trying to read such entities I get mentioned exception.
Are the any solution for the 1.3.0 ?
Thanks,
Michael

Hi,
I have a similar issue with 1.3.0 however it arises when the
types
are the same and not related to inheritance of any type.
The work around suggested doesn't seem to work. Is the workaround
valid for 1.3.0?
thx,
Conor

SDK 1.2.8 contains a new check that detects if one of your JDO
or JPA model
objects has two relationship fields of the same type. For
example:
class A {
List<B> bList;
List<B> anotherBList;
}
Unfortunately I was a little too aggressive with this check, so
the
following also run afoul of the check:
abstract class B {}
class C extends B {}
class D extends B {}
class A {
List<C> cList:
List<D> dList;
}
If you get an exception that says
Class XXX has multiple relationship fields of type YYYY. This
is not yet
supported.
and your class hierarchy resembles the one above, you can
disable this check
by with the following config property:
<property
name="datanucleus.appengine.multipleRelationsOfSameTypeAreErrors"
value="true"/>
We'll get this fixed shortly.
Sorry for the trouble,
Max
