Node naming

[ms...@email.cz]

Hello,

I just realized following behaviour in node naming when I use the same node name for children. Say I have 2 nodes with the same name. Then Jackrabbit uses following path to distinguish them: /path/node and /path/node[1]. If I delete first node '/path/node' then node originally with absolute path '/path/node[1]' will now have absolute path '/path/node'.

It means I cannot use path '/path/node[1]' to locate second node. I must use either jcr:uuid or use unique node names for my nodes

Am I right?

Thanks

Marek

The first one should be available as both node and node[1]; the second 
one as node[2]. Until you delete the first, of course.

First of all sns are pretty tricky and usually not recommended unless really
needed [0].  As I recall the array worked like a stack, last in, first out
when referencing without the array index, so that means the entire array
shifts when you do that. See also [1] and [2].

Yes you are right, but I'd suggest avoiding them entirely if possible. If
you don't already know, you can accomplish that by using a node type that
has sns disabled (custom, or a default one like nt:folder).
