p：fileUploadを使用して、アプリケーションに画像をアップロードしたいと思います。
ここでは、正しく機能するデモプログラムを作成します。しかし、JSFテンプレート内に配置すると、外観が変更され、FileUploadEventが呼び出されません。
これが私のjsfページです:(動作中）// ------------
<h:form enctype="multipart/form-data">
<p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload}"
mode="advanced"
update="messages"
sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"
auto="true"/>
<p:growl id="messages" showDetail="true"/>
</h:form>
//--------バッキングBean
@ManagedBean
public class FileUploadController
{
public void handleFileUpload(FileUploadEvent event) {
FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
try {
String path = FacesContext.getCurrentInstance().getExternalContext().getRealPath("/");
SimpleDateFormat fmt = new SimpleDateFormat("yyyyMMddHHmmss");
String name = fmt.format(new Date())
+ event.getFile().getFileName().substring(
event.getFile().getFileName().lastIndexOf('.'));
File file = new File(path + "/" + name);
this.setFileName(name);
this.setState(Boolean.TRUE);
InputStream is = event.getFile().getInputstream();
OutputStream out = new FileOutputStream(file);
byte buf[] = new byte[1024];
int len;
while ((len = is.read(buf)) > 0) {
out.write(buf, 0, len);
}
is.close();
out.close();
} catch (Exception e) {
System.out.println("Exception in file io");
}
}
}
// -------テンプレート内に配置すると、次のように機能しません

私は何が問題なのかを見つけるためにたくさん努力しますが、私は解決策を見つけることができません
