When trying to delete multiple nodes, every other node does not get deleted

[steven-mercatante]

Say you fetch five entities from the DB, and want to delete each one. Iterate over the collection, wrapping each entity as a node, and then call $node->delete(). Only some of the nodes will be deleted, and the pattern seems to be that every other entity is not deleted. So, if you tried deleting the five entities, the second and fourth entities would not be deleted.

Looking at NodeWrapper::delete(), if you output the result of $qb->getQuery()->execute() (line 1182) you'll get back 0 for every other query.

After more testing, it looks like the following three lines within NodeWrapper::delete() are somehow responsible:

$first = $oldRgt + 1;
$delta = $oldLft - $oldRgt - 1;
$this->shiftRLRange($first, 0, $delta, $oldRoot);

I was able to work around the issue by reversing my original array of entities, so that the ones with higher rgt values were processed before those whose rgt values were lower.
