Link attribute does not work in model using Business Publisher

My need is to link an object to a document in business publisher.

I use the attribute "Link 1", witch works fine in the Business Architect, using the "Run" features, it opens the document linked.

I supposed that in the Business Publisher this attribute was implemented as an html Hyperlink.

Unfortunatly it is a simple text form.

Here an example (see the red ellipse) :

Many thanks
