OK, now I have in my managed bean : | @In(required = false) | private City selectedCity; | public City getSelectedCity() {return selectedCity;} | public void setSelectedCity(City c) {this.selectedCity = c;} | with interfaces declared ..... <h:selectOneMenu | id="selectCity" | value="#{selectedCity}" | required="false"> | | <s:selectItems | value="#{register.cities}" | var="c" | label="#{c.postalCode} - #{c.name}" | /> | | <s:convertEntity /> | </h:selectOneMenu> When I submit my form, seam performes validation, but my selectOneMenu validation fails, and then, values are never submited ..... why a selectOneMenu validation can fail ?
