I am attaching a Quickstart project to help reproduce the problem.
On the home page, middle click in the email address shown (usually
this will take a user to a detail page, but in this case it just
prints a message). After that, any click on a link in the page will
cause a component not found exception.
Thanks for all your help.

Can anyone explain to me why this does not work with
AjaxFallbackDefaultDataTable, but does with DefaultDataTable.
Does anyone know of a solution for this problem?

Since AjaxLink is AJAX and not a proper link, then it does
behave as a normal link, i.e. middle click (open link in new
tab or new window) does not trigger the AJAX click even,
which means you cannot chose to open the link in a new page.
back to square one, except that know I know is a problem with
AjaxFallbackDefaultDataTable, not with DataTable.

Jeremy, the code is below.
I did notice something while researching/testing more.
The LinkPanel solution DOES work for a DataTable. The
problem starts when changed to a
AjaxFallbackDefaultDataTable.
I did testing based in the datatable example in the
wicket examples.
Maybe using an AjaxLink instead of a normal link in the
table is the right answer.
Code is mostly taken from the page linked in the original
email
public abstract class LinkPanel<T> extends Panel {
private static final long serialVersionUID =
2062173455224348354L;
public LinkPanel(final Item<?> item, final String
componentId,
final IModel<T> model, final String property) {
super(componentId, model);
AjaxLink<T> link = new AjaxLink<T>("linkCell") {
private static final long serialVersionUID =
2574434147588617330L;
@Override
public void onClick(AjaxRequestTarget target) {
LinkPanel.this.onClick();
}
};
add(link);
link.add(new Label("label", new
PropertyModel(model,property)));
}
protected abstract void onClick();
}
----------------- Usage ---------------
public class LinkPanelPage extends WebPage {
public LinkPanelPage() {
Form form = new Form("form");
final LinkPanelListProvider provider = new
LinkPanelListProvider();
List<IColumn> columnList = new ArrayList<IColumn>(3);
//columnList.add(new PropertyColumn(new
Model("eMailAddress"),"eMailAddress"));
columnList.add(new AbstractColumn(new
Model("eMailAddress"), "eMailAddress") {
private static final long serialVersionUID =
-1822504503325964706L;
@Override
@SuppressWarnings("unchecked")
public void populateItem(Item cellItem,
String componentId, final IModel rowModel) {
cellItem.add(new LinkPanel(cellItem,
componentId, rowModel, getSortProperty()) {
private static final long
serialVersionUID = -4615958634366803506L;
@Override
protected void onClick() {
System.out.println("clicked on
link");
}
});
}
});
columnList.add(new PropertyColumn(new
Model("firstName"),"firstName"));
columnList.add(new PropertyColumn(new
Model("lastName"),"lastName"));
AjaxFallbackDefaultDataTable table = new
AjaxFallbackDefaultDataTable("link-panel-table",
columnList, provider, 3);
form.add(table);
add(form);
}
}
