Hi,
I get NPE during call to node.getNodes() in JackRabbit 2.4.3. Not sure what the
cause is.
The failing line is:
if (!data.getParentId().equals(parentId)) {
When error occurs, data.getParentId() return null. Could it be because item in
data is transient?
Is this a bug in JackRabbit or should I not be allowed to iterate over
transient items?
Thanks for any insight,
Jan
