Answer 1

Probably, its because you are using ice:form and submitting it through h:commandButton. Change your commandButton to ice:commandButton then retry.

Change:

<h:commandButton type="submit" value="#{msg.Login}" 
     action="#{loginBean.login}" />

to:

<ice:commandButton type="submit" value="#{msg.Login}" 
    action="#{loginBean.login}" />
