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!
