Hello Martin & List,
Yes, okay, but is it really necessary for me to define an own model class?
Would it not be much more straightforward to just instantiate one of the
existing models, like
new FileUploadField("UploadFileField", new Model<List<FileUpload>>()));
or some Model.of() variant ?
However, new Model() does not work, as FileUpload is not Serializable...
(and sorry for the delayed "bump" post today, sync issues with the
mobile ;-)
Any ideas what better to use ?
Thanks & Cheers, Tom.

Hello,
I have an outer form, with a CPM for a business entity.
An inner form
Form<Void> uploadImageForm = new Form<>("UploadImageForm");
has a
FileUploadField uploadImageField =
new FileUploadField("**UploadImageField");
and when I submit the inner form, wicket tries to find
getters/setters for UploadImageField in my business entity,
which obviously are not there:
WicketRuntimeException: No get method defined for class: class
XXXBusinessEntity expression: UploadImageField
I tried many things to work around this problem, including
Form<Void> uploadImageForm = new Form<>("UploadImageForm", null);
and
uploadImageField = new FileUploadField("**UploadImageField", null);
and
setModel(null)
and some more, however the only way to really get rid of this
I found is:
FileUploadField uploadImageField = new
FileUploadField("**UploadImageField",
new UploadFieldModel());
static class UploadFieldModel implements
IModel<List<FileUpload>> {
List<FileUpload> f;
@Override
public List<FileUpload> getObject() {
return f;
}
@Override
public void setObject(List<FileUpload> object) {
f=object;
}
@Override
public void detach() {
}
}
That doesn't sound too reasonable, does it ?
I do not need or want the value to be put to any model, is there any
more sensible way to do this ? (wicket 6.8.0 - will update soon)
Actually this is the correct way.
Wicket needs to store the data somewhere. Usually 'somewhere' is the form
component's model.
By using 'null' or by not setting anything the component tries to use its
parent's model.
