Hyperlink path root is missing in XML Forms

Hi,

I have created a XML Form.

In the Edit form I have a Browser control to store other existing xml file as node.

In the Show form, I create link based on the Shema Reference got in the Edit form but when I test my form the root of the link is always missing. (/irj/go/km/docs).
My link start with 

<servername:port>/documents/<folder path>/100927cf-79f2-3310-088b-9bf1d51b8dea.xml
and I need

<servername:port>/irj/go/km/docs/documents/<folder path>/100927cf-79f2-3310-088b-9bf1d51b8dea.xml

Do I have to put the root path somewhere in the settings ?

Here find the properties of my link in the Show form:
