lymoreira 9 de mai. de 2012
veja se está claro para entender.
public void remover ( ActionEvent ev ) throws IOException {
try {
faqBean . remove ( faqTO );
setMensagem ( MENSAGEM . getProperty ( "MA044" ));
} catch ( IOException e ){
setMensagem ( e );
}
}
public void remove ( FaqTO to ) throws IOException {
Ipptb006Faq entity = setFaq ( to );
em . getTransaction (). begin ();
em . remove ( em . find ( Ipptb006Faq . class , entity . getId ()));
em . getTransaction (). commit ();
}
private Ipptb006Faq setFaq ( FaqTO to ) throws IOException {
Ipptb006FaqPK FaqPK = new Ipptb006FaqPK ();
Ipptb006Faq Faq = new Ipptb006Faq ();
if ( to . getNuFaq () != null && ! to . getNuFaq (). equals ( 0 )) {
FaqPK . setNuFaq ( to . getNuFaq ());
FaqPK . setIcCcaUl ( to . getIcCcaUl ());
} else {
Query query = em . createNativeQuery ( "select nextval from nextval('IPPSQ006_FAQ_NU_FAQ_seq')" );
Integer numero = new Integer ( String . valueOf ( query . getSingleResult ()));
FaqPK . setNuFaq ( numero );
FaqPK . setIcCcaUl ( to . getIcCcaUl ());
}
Faq . setId ( FaqPK );
Faq . setDePergunta ( to . getDePergunta ());
Faq . setDeResposta ( to . getDeResposta ());
return Faq ;
}

fazer <f:setPropertyActionListener
target="#{faqMB.faqTO.nuFaq}"
value="#{item.nuFaq}" />não funciona?
esse valor realmente não está nulo ?
lymoreira 9 de mai. de 2012
então eu tentei das duas maneiras ele não ta setando nada, vem nulo tambem
Rodrigo_Sasaki 9 de mai. de 2012
Tente colocar seu método no action ao invés de actionListener ,
e tire o ActionEvent que ele recebe.

então tentei fazer isso agora ele me mando uma mensagem de erro assim:

é, não entendo nada de Portlets hehehe…
mas eu uso dessa maneira que te disse, um <f:setPropertyActionListener> dentro de um a4j:commandButton
a única coisa que imagino é que esse atributo que você está enviando pode realmente estar nulo.
mas vou deixar alguém que entende melhor te ajudar
PhilipeSC 9 de mai. de 2012
<a4j:keepAlive ajaxOnly=“false” beanName=“NomeDoObjeto” />
tenta por o KeepAlive, e verifica se seu objeto no managed bean está setado como request, se for é isso. e poe no seu botao do a4j o atributo AJAXSINGLE=FALSE
