[jira] [Resolved] (JCR-3050) NullPointerException on removing a
node acquired from search result
Posted by "Alex Parvulescu (Resolved) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/JCR-3050?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alex Parvulescu resolved JCR-3050.
----------------------------------
Resolution: Fixed
Fix Version/s: 2.5
The NPE happens because you re trying to delete the root node.
(Try running the same query and printing the path of the nodes you get)
I've fixed the NPE, but your scenario is still not going to work as you cannot delete the root node. You'll get a ConstraintViolationException: "Cannot remove root node."
Fixed in revision #1240198.

hi, you are welcome :)
by the way, you're not supposed to close the issue ;) just leave it as 'resolved' and when it ships it will turn into 'closed'.

[jira] [Closed] (JCR-3050) NullPointerException on removing a node
acquired from search result

David Buchmann closed JCR-3050.
-------------------------------
oh, ok. guess with the right exception i will understand what i do wrong :-)
actually the root node is reported as something else than nt:unstructured, so it was not so obvious to me.
thanks for the cleanup
