WicketNotSerializableException withi FileUpload
Hello fellow Wicket users,
I am getting a org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException:
Unable to serialize class:
org.apache.wicket.util.io.DeferredFileOutputStream exception when I
added a file upload feature to my AddProductForm.
My form is serialiazable yet I don't which of its child components are
not serializable. Can anyone shed any light on this?
Cheers,
James.
Here is my Page class:
public class AddProductPage extends AdminPage {
private static final long serialVersionUID = 1L;
@SpringBean(name="adminService")
private AdminService adminService;
public AddProductPage(Product product) {
MenuBorder border = new MenuBorder("libBorder");
border.add(new FeedbackPanel("feedback"));
border.add(new AddProductForm("productForm", product));
add(border);
}
private final class AddProductForm extends Form {
private static final long serialVersionUID = 1L;
private FileUploadField fileUploadField;
public AddProductForm(String id, Product product) {
super(id, new CompoundPropertyModel(product));
setMultiPart(true);
add(new RequiredTextField("name"));
add(new RequiredTextArea("description"));
add(new RequiredTextField("sellValue", BigDecimal.class));
add(new RequiredTextField("units", Long.class));
add(new CheckBox("onSell"));
add(new DropDownChoice("category", catalogService.getCategories()));
add(new DropDownChoice("manufacturer", catalogService.getManufacturers()));
add(fileUploadField = new FileUploadField("fileInput", new
Model(fileUploadField)));
setMaxSize(Bytes.megabytes(100));
}
@Override
protected void onSubmit() {
final FileUpload upload = fileUploadField.getFileUpload();
if (upload != null)
System.out.println("File is not empty! Whoo hooo!");
else
System.out.println("File is empty! Whoo hooo!");
fileUploadField.detachModels();
/**Product product = (Product) getModelObject();
product.setEntryDate(new Timestamp(System.currentTimeMillis()));
product.setImageURL("uploads/");
System.out.println(product.getCategory());
adminService.saveProduct(product);
setResponsePage(ViewProductsPage.class);**/
}
}
}

I removed the Model instantion from the FileUploadField and this issue has gone.

Re: WicketNotSerializableException withi FileUpload
Posted by Johan Compagner <jc...@gmail.com>.
Ok the problem is that somehow you are holding on to a FileUpload in your
page
And those are not meant to be kept over requests.
it seems that you keep it if i read it right in a normal Model:
[class=org.apache.wicket.model.Model]
private java.io.Serializable
org.apache.wicket.model.Model.object
[class=org.apache.wicket.markup.html.form.upload.FileUpload]
How do you create the FileUploadField?
I guess with a normal new Model()?
I think we need to fix that somehow in the detach of the FUF because if the
model is set
we should look into the model and if it is a FileUpload get rid of it or
something.

Re: WicketNotSerializableException withi FileUpload
Posted by James Perry <ja...@gmail.com>.
Hello Johan,
Thanks for the repsonse. :-)
All I have done is follow the code within theSingleFileUpload example
in wicketstuff.com. Is this a bug or am I doing something wrong? I am
using Wicket 1.3.0-beta4 and here is the stack of the exception:
ERROR - Objects - Error serializing object class

Re: WicketNotSerializableException withi FileUpload
Posted by Johan Compagner <jc...@gmail.com>.
what is the full stack of the exception?
because who does have that field?
Streams should always be transient because those can't be serialized
whats the wicket version?
