I have to refresh a subnode I have previously loaded dynamically; the easiest way would be
– delete all the children of the group
– reload all the children using a service
*)
but for doing this I would need to iterate through the nodes of a specific group: is this possible?
if not, I would simply
– delete the group
– reload the children using a service
*)
but for doing this I would need to know the position of the node I’m going to remove, as I need to insert the new groupnode exactly at the same position;
at the moment I’m just able to insert it at the end
a simple way to iterate through nodes would be fine …
