So, here's what I do : At the home level, I create a project with the create new ressource on the upper right corner, I select the ressource type (project) and provide the URI myproject, submit the form.Here I am redirected to the configuration page of that resoure /projects/myproject

Then, I want to create a new ressource from that node so a click on the link Create new ressource on the upper right corner.

Here comes the error : URI ls://myserver/projects/projects/myproject does not exist

I Hope this can help you to see what's wrong
