to usando uma tree. ELe chega a exibir a tree, mas qdo seleciono algum item e mando salvar...ele estoura esse erro
minha view<p:panel id="panelItens" style="margin-top: 10px; margin-bottom: 10px; width: 500px;" header="Itens Produtos">
root: <h:outputText value="#{itensManagedBean.root}" />
<p:tree value="#{itensManagedBean.root}" selectionMode="checkbox" var="no" expanded="true" expandAnim="FADE_IN" collapseAnim="FADE_OUT" selection="#{itensManagedBean.nosSelecionados}" propagateSelectionUp="true" propagateSelectionDown="true">
<p:treeNode>
<h:outputText value="#{no}" style="margin-left: 10px;"/>
</p:treeNode>
</p:tree>
</p:panel>
<p:commandButton value="Salvar" action="#{itensManagedBean.salva()}" update="panelItens"/>
public void salva() {
System.out.println("entrou no botao salva itens");
if (produtoSelecionado.getCodigo() == 0) {
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, "Nenhum produto SELECIONADO", "Erro"));
}
else {
try {
System.out.println("nosSelecionados: " + nosSelecionados);
for (TreeNode no : nosSelecionados) {
if (no.isLeaf()) {
salvaPai(no);
}
}
carregaPermissoesUsuario();
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Itens Salvos", "ItensSalvos"));
}
catch (SQLException ex) {
Logger.getLogger(ItemManagedBean.class.getName()).log(Level.SEVERE, null, ex);
} }
}
Mas nao chega nem imprimir a primeira linha (o system.out.println não é executado) :shock:
