Duvida Geração de mensagem de confirmação JavaScript

Boa Noite Pessoal, eu estou desenvolvendo uma tela onde eu tenho um botão que gera um arquivo.

Quando eu clico nesse botão, ele verifica se existe informação nula e caso exista, não gero o arquivo.

Eu gostaria de fazer via java script ou de alguma outra forma , que quando encontrar informacoes nulas o sistema pergunte se desejo gerar assim mesmo, ecaso a resposta seja afirmativa, continue o fluxo e gere o arquivo.

Alguem tem alguma ideia ?

Segue como esta meu button e como eu estou controlando a geração do arquivo atualmente :

<p:commandButton value="Gerar" update="formGerarDoc,msggerardocs" 
                     action="#{gerarDocumentoController.gerarDoc}" image="ui-icon ui-icon-check"   
                   		 	oncomplete="onEditComplete(xhr, status, args)"   style="font-size: 12px" immediate="true" ajax="false">
                   		 	<p:ajax  listener="#{gerarDocumentoController.changeValue}" update="formGerarDoc,msggerardocs"/>
         </p:commandButton>

public void gerarDoc() {
		final StringBuffer buffer = new StringBuffer();
		FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_WARN, "SGD", "Informações Nulas");
		boolean loggedIn = false;
		boolean tagsNulas = false;

		if (idTemplate != null && idTemplate!=0){
			loggedIn = true;
		}
		
		for (InformacoesFaltantes faltantes : listaTagsTemplate) {
			loggedIn = true;
			if (faltantes.getInformacaoTag() == null || faltantes.getInformacaoTag().isEmpty()) {
				loggedIn = false;
				tagsNulas = true;
				//msg = new FacesMessage(FacesMessage.SEVERITY_WARN, "SGD", "Informações Nulas");
				break;
			}
		}
		
// Aqui eu queria perguntar para o usuario se deseja gerar mesmo com informaçoes nulas
/*		if (tagsNulas){
                    // if (confirmação do usuario for positiva){
			loggedIn = true;
                      }
		}
*/
		if (loggedIn){
			
			Gravar();
			msg = new FacesMessage(FacesMessage.SEVERITY_INFO,"Documento Gerado", null);
		}
		
		FacesContext.getCurrentInstance().addMessage(null,msg);
	}

JSP + primefaces 3 RC + Majorra 2.0 …

Eu nao conheço direito tudo que estou utilizando … Acho que é isso.

usa o confirmDialog

fabio_lpontes

Fmz ateh dá para para usar o confirmDialog, mas como eu faço para esse confirm dialog aparecer apenas quando não encontrar informação ?

a ideia eh o botão “gerar” validar se tem informação nula … se tiver, abrir esse dialog perguntando se deseja gerar assim mesmo …

Eu to empacado para condicionar a abertura desse dialog …

E
evefuji

vc coloca um rendered nele de acordo com sua lógica, e coloca ele dentro de um objeto primefaces (por exemplo, p:outputPanel). Quando clicar no botão que vai verificar se existe ou não, você dá um update no pai desse p:confirmDialog.

Mas como eu vou chamar o confirmation ? por mais que eu condicione ele em um rendered, eu preciso de um evento para dar show no dialog … eu tava pensando em asar java script … , mas ta dando um erro … alguem sabe onde eu to errando ? (segue o codigo e o erro que ta dando)

esse erro ta ocorrendo porque o comando “RequestContext context = RequestContext.getCurrentInstance();” ta retornando null … Se eu trocar o botão para ajax true, esse comando retorna valor, contudo não gera documento …

alguem sabe o que ta ocorrendo ?
