What does this warning mean: [org.openide.nodes.DefaultHandle]: parent could not find own child??

[erisch]

Hello!

I get an error in the logs for an application I develop. I'm
implementing an explorer view for some nodes and everything seems to
work more or less correctly at the moment. I just got this message
sometimes when testing my application and I couldn't find really helpful
information about it.

Is this an error or just a warning? Can anyone explain what it means and
how to fix it? Thanks!

Printed by DefaultHandle, which is the default impl of node path
serialization, which might be used when saving the expansion state of a
tree view. The warning means that

node.getParent().findChild(node.getName()) != node

which might occur if your node names are not sufficiently distinct from
those of their siblings.

Thanks a lot for this ultra fast answer ;) Chances are good that this is
the reason. I'll take a look at the getName() method...
