[teneo] bidirectional OneToOne containment association - container not set in child object [message #602125] Sat, 03 February 2007 18:46

Hi alltogether,

on CVS head version of teneo and previous versions:

I can successfully save and load a containment hierarchy with a one-to-one
association between a container and a child, and this hierarchy is displayed
correctly in the editor tree. However, if I invoke a method on the child which
navigates to the container, either via the named association or the eContainer()
I found that the container reference is null. Only the container has a reference
set to the child, but not vice-versa.

I tried to play around with the code here in HibernatePersistableEList:

// disabled for now as containers are persisted by hibernate anyway
if (false && isContainment()) {
final int featureID = getEStructuralFeature().getFeatureID();
for (int i = 0; i < objs.length; i++) {
if (objs[i] instanceof InternalEObject) {
EContainerRepairControl.setContainer(owner, (InternalEObject) objs[i],

I've set the constant to "true" but it did not have any positive effect.

Any help? How or when do you expect hibernate to set both side of the association?
