No translation in pviews

Problem

In a pview, from cubicweb import _ and self._cw._ do not translate, so it just returns the string that was given as argument. It is also the case of self._cw.user._cw._.

Remarks

  • However self._cw.user.prefered_language() returns a good result.
  • It is at least the case with version 3.26.18 of CubicWeb.

Technical notes

From where is it given?
