Hi Andrea,
i have tried your saying again and solved the problem :) thank you so
much...
the solution is,
final FileUploadField fileUploadField = new FileUploadField("fileUpload",
new IModel<List<FileUpload>>() {
public List<FileUpload> getObject() {
return null;
}
public void setObject(List<FileUpload> object) {
}
public void detach() {
}
});
form.add(fileUploadField);
....
...
.....
AjaxButton submit = new AjaxButton("submit") {
@Override
protected void onError(AjaxRequestTarget target1, Form<?> form)
{
feedbackPanel.setVisible(true);
super.onError(target1, form);
target1.add(wrapper);
}
@Override
protected void onSubmit(AjaxRequestTarget ajaxRequestTarget,
Form<?> form) {
user1.setPhoto(fileUploadField.getFileUpload().getBytes());
<-----important
user1Dao.save(user1);
ajaxRequestTarget.add(wrapper);
}
};
form.add(submit);
wrapper.add(form);
