Thanks for the example :) Indeed, the documentation is a bit outdated since Spec is still improving a lot, a changing a bit in its API. One of my goal now is to write proper doc for Spec :) Ben On Oct 11, 2013, at 8:23 AM, btc(a)openInWorld.com wrote: > > I found it hard to find documentation on Spec beyond [1],[2],[3], some of which seem to have changed some syntax since they were written.

I found it hard to find documentation on Spec beyond [1],[2],[3], some of which seem to have changed some syntax since they were written. I've been piecing things together to work out how to set the selected item with the simplest example I could.

Also, a trailing slash is added, that could be a problem for the server as well. Else, you will have to look at the stack trace in the debugger and try to understand what is going on.

Yes, when I access the same share from a browser I get a directory listing which shows the .mcz files. I'll have to check if I can actualy load the files copied to the share.
