Witam,
w ramach treningu próbuję stworzyć forum dyskusyjne. Do tego celu używam JSF i Hibernate. W szablonie w nagłówku umieściłem formularz logowania. Wszystko jest ok podczas logowania ze strony głównej. Podczas logowania z podstrony występuje błąd. Logowanie odbywa się w metodzie sprawdz. Może wiecie w czym tkwi problem?
formularz:
<h:form>
<table>
<tr>
<td>
Login: <h:inputText id="login" value="#{logBean.login}" autocomplete="false" ></h:inputText>
</td>
<td>
Hasło: <h:inputSecret id="haslo" value="#{logBean.haslo}" autocomplete="false"></h:inputSecret>
</td>
<td>
<h:commandButton label="Loguj" action="#{logBean.sprawdz}" id="submitButton" value="Loguj"/>
<h:commandButton label="Rejestruj" action="#{logBean.rejestruj}" id="submitButton2" value="Rejestruj"/>
</td>
</tr>
</table>
</h:form>
logBean:
package bean;
import entity.Users;
