p:fileUpload não funciona

Programação Java
#1

Olá amigos

estou com um problema que o p:fileUpload não está executando o fileUploadListener.

web.xml

		    <p:commandButton value="Carregar" ajax="false" actionListener="#{credenciamentoBean.upload}" />
		</h:form>

Bean.java

	public void loadFile(FileUploadEvent event) throws IOException {
	if (imagem != null){
		imagem.getStream().reset();
	}			
	
	imagem = new  DefaultStreamedContent(new ByteArrayInputStream(event.getFile().getContents()));
		
	imagem_temp = new  DefaultStreamedContent(new ByteArrayInputStream(event.getFile().getContents()));
	setTmpFoto(imagem_temp.getStream());
    this.setTempFoto(toByteArray(getTmpFoto()));
    
}

se eu colocar com :commandbutton ele executa o bean mas o file fica null.

    public void upload() {
    if(this.file != null) {
    	
    }
}

Olá ardenghe

no p:fileupload tem um fileUploadListener que não está sendo executado, mas se eu colocar um <p:commandButton value=“Carregar” ajax=“false” actionListener="#{credenciamentoBean.upload()}" o método upload é executado mas a variável file não é setada fica nula.

 <p:fileUpload value="#{credenciamentoBean.file}" mode="simple" skinSimple="true" />

 public void upload() {
if(this.file != null) {
	
}

Estou usando o PrimeFaces 6.1 e Boostrap 3.3.7

muito obrigado
