app-crud + app-navigate

Happy new year.

When I  use (thanks to Louis Moore for his answer)

<menu title="Person"
      model="crud.list-seq"
      parameters="&amp;persistent=payroll.person&amp;domain=default"
      />

I get the same html page than with

<menu title="Person"
      model="crud.list"
      parameters="&amp;persistent=payroll.person&amp;domain=default"
      />

that is without either the navigate menu or the register header info.

If I swapp models "nav.navigate" and "crud.list-for-seq" in 
crud.list-seq, I get only the navigate menu, ie the last one output.

Any help?

Regards
