I have discovered following: 1. When I come to page detail.jsp for the first time, param name is included in URL (but I don't need that here :) ). 2. When param tag isn't as a child of redirect tag, then after invoking search.actionSearch param name isn't included in URL although it is defined in page tag. Reference guide: anonymous wrote : Any navigation rule with a redirect to the view id transparently includes the request parameter. The | value of the parameter is determined by evaluating the value binding at the end of the invoke application | phase. 3. Model isn't updated according to param name (GET request with name param). Reference guide: anonymous wrote : | The param declaration is bidirectional, just like a value binding for a JSF input | When a non-faces (GET) request for the view id occurs, Seam sets the value of the named request parameter | onto the model object, after performing appropriate type conversions.
