Please create a quickstart.
Wicket usually shows which field is not Serializable. Not sure why it
doesn't work for you.

Hi Guys,
It's my fault. It isn't a bug of wicket. After another 2 hours debugging I
finally found the root cause in the code of my app. There is a private
static class XXX{} in a very deep hierachy of one of my util class. And that
private class XXX hasn't implements the Serializable.
But if Wicket can throw a more friendly serializing exception like (the
class xxx or field fff can't be serialized) will be great helpul - given
that, this kind of missing serializing private class issue will be fixed in
few minutes instead of two days.
Thanks,
James

Hi Martin,
I've tried the wicket 6.3 quickstart but can't reproduce it. But after more
deep debug I've found the root cause on my app -
1. On my html there is a Sortable list.
2. I've implemented some code to extends
org.apache.wicket.extensions.markup.html.repeater.util.SortableDataProvider
3. then on the method -
@Override
protected void populateItem(final Item item) {..}
I've added item.add() to get list data
4. if I set a WebMarkupContainer wmc.setVisible(false); and call
item.add(wmc) then will cause the serializable exception.
Does it a bug of Wicket or do I need call some api after setVisible(false)?
Thanks!

"SEVERE: " looks to me like java.util.logging is in use.
Upgrade to Wicket 6.3.0 and try again. If you can reproduce it in a
quickstart application then please attach it to a ticket in Jira.

I am using Wicket6.1 and logback. The logback keep writing this serializing
error to its DB. Do you know why this exception happenned? I've double
checked my wicket pages relevant code but found nothing about this
exception. Seems everything should be able to be serialized.

Hi,
Which version of Wicket is this ?
Here is the code:
try
{
writeObjectMethod = cls.getDeclaredMethod("writeObject",
new Class[] { java.io.ObjectOutputStream.class });
}
catch (SecurityException e)
{
// we can't access / set accessible to true
writeObjectMethodMissing.add(cls);
}
catch (NoSuchMethodException e)
{
// cls doesn't have that method
writeObjectMethodMissing.add(cls);
}
i.e. NoSuchMethodException is catched and never logged.
Do you use SecurityManager ?
