ben resim yüklemek için Iframe'i kullanıyorum. ProductPanel.html ürününe bir iframe ekledim. Ajax submit kullanarak dosya yüklemek mümkün olmadığından.
UploadIframe.java
protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
DynamicImage imageEntry = new DynamicImage();
if(uploadField.getFileUpload() != null && uploadField.getFileUpload().getClientFileName() != null){
FileUpload upload = uploadField.getFileUpload();
String ct = upload.getContentType();
if (!imgctypes.containsKey(ct)) {
hasError = true;
}
if(upload.getSize() > maximagesize){
hasError = true;
}
if(hasError == false){
System.out.println("######################## Image can be uploaded ################");
imageEntry.setContentType(upload.getContentType());
imageEntry.setImageName(upload.getClientFileName());
imageEntry.setImageSize(upload.getSize());
if(imageEntry != null){
try {
save(imageEntry,upload.getInputStream());
} catch (IOException e) {
e.printStackTrace();

}else{

System.out.println("#################### Error in image uploading ###################");

ben bağlantısı mevcut olduğunda "Ürün Ekle" hangi ilk sayfaya yönlendirmek için setResonsePage() kullanıyorum. Böylece yenilenen sayfanın yeni ürün bilgilerine sahip olmasını sağlayın.
Sorunum, modal pencerenin window.close() 'da kapanmaması ve bu pencerenin içinde yenilenen sayfayı almamdır.
Benim gereksinim, Modal pencerenin kapanması ve sayfanın yenilenmesi gerektiğidir. Benim setResponsePage() içinde Parentpage.class iletiyorum.
Her türlü yardım ve tavsiye takdir edildi! Şimdiden teşekkürler.
