The problem is that populateItem() is called at render time, and that
the onClick() is called when you have been to the client and are
processing the component listener. I have falled into this trap myself,
and I can only advise you to use the following code, which is a lot more
safer in any context:
final PageableListView list = new PageableListView("rows", data, 10)
{
public void populateItem(ListItem listItem)
{
listItem.add(new Link("sjs") {
public void onClick() {
MyObject value = (MyObject) getParent().getModelObject();
System.out.println(value.getName());
}
}
};
Note that all final keywords have disappeared and no hidden magic is
remaining on keeping references to object between render and handling time.

Maybe it's just late, but I can't seem to answer this question myself.
Will each model object in my list exist after the request has finished
with the following code, assuming that the list is wrapped in a
detachable model:
final PageableListView list = new PageableListView("rows", data, 10)
{
public void populateItem(final ListItem listItem)
{
final MyObject value = (MyObject) listItem.getModelObject();
listItem.add(new Link("sjs") {
public void onClick() {
System.out.println(value.getName());
}
});
}
};
or how about this:
final PageableListView list = new PageableListView("rows", data, 10)
{
public void populateItem(final ListItem listItem)
{
final MyObject value = (MyObject) listItem.getModelObject();
final String name = value.getName();
listItem.add(new Link("sjs") {
public void onClick() {
System.out.println(name);
}
});
}
};
