解决了从另一个控制器使用组件PrimeFaces“graphicImage”加载图像时出现的问题我现在的问题是当我将图像烧到本地地址时，我生成PrimeFaces错误，但显然不会影响我的目前的功能。录制控制台图像graphicImage Primefaces时出错？
的图像加载使得setAddAttributes方法，问题是，我注意到的是，当我去的方法来记录setSaveAttributes会发生什么，记录的顺利我的数据，但我这个例外在控制台中，我认为它必须做的工具是SessionScoped管理（但它不承认我和我管理生成一个空）。
<p:graphicImage value="#{mGraficoImagen.graphicImage}" cache="false" />
主管理控制器：
@ManagedBean
@ViewScoped
public class CMantConsultaProductosList {
@ManagedProperty(value="#{mGraficoImagen}")
private MGraficoImagen mGraficoImagen;
private MProductoBean mantForm;
@PostConstruct
public void setViewAtributes() {
MProductoBean mantForm = new MProductoBean();
mantForm.setVnomImagen("fancoil-fn.png");
}
public void setAddAttributes(ActionEvent e) {
StringBuilder archivoImagen = new StringBuilder();
archivoImagen.append("C://images//");
archivoImagen.append(mantForm.getVnombreImagen());
this.mGraficoImagen.setGraphicImage(new DefaultStreamedContent(new FileInputStream(archivoImagen.toString()),
"image/png",
mantForm.getVnombreImagen()));
}
public void setSaveAttributes(ActionEvent e) {
.........
iProductoService.grabarProducto(mantBean);
}
/* get and set */
}
的Util管理：
@SessionScoped
@ManagedBean(name = "mGraficoImagen")
public class MGraficoImagen implements Serializable {
private static final long serialVersionUID = 1L;
private StreamedContent graphicImage;
/**
* @return the graphicImage
*/
public StreamedContent getGraphicImage() {
return graphicImage;
}
/**
* @param graphicImage the graphicImage to set
*/
public void setGraphicImage(StreamedContent graphicImage) {
this.graphicImage = graphicImage;
}
}

显然，错误生成的第二个叫我管理@SessionScoped，那么你应该在那种情况下......？ – Hernando
