[NodeBundle] Duplicate pages in admin menu

[dannyvw]

We have a "multi_lang" configuration with multiple locales (nl/en/de). If the page is not translated then it will show the page multiple times in the admin menu. This method https://github.com/Kunstmaan/KunstmaanBundlesCMS/blob/7.x/src/Kunstmaan/NodeBundle/Repository/NodeRepository.php#L262 returns the same node multiple times.

It can also be solved to use $this->treeNodes[$parent_id][$nodeInfo['id']] = $nodeInfo; on this line https://github.com/Kunstmaan/KunstmaanBundlesCMS/blob/7.x/src/Kunstmaan/NodeBundle/Helper/Menu/PageMenuAdaptor.php#L154
