Re: [Exist-open] xmldb:rename shows incorrect behaviour on collections with subcollections (eXist 5.2)

[Nick S. <nsi...@nu...>]

Have you tried re-indexing your collections? The reason I suggest this 
is because I sometime run into perplexing situations where my queries 
are not working and I re-index and suddenly they query works. This just 
happened to me yesterday. I don't really have an explanation on why the 
collection needs re-indexing but it is happened enough time in the past 
that it is a technique I always remember to try if I am really confused 
why my query is not working.
