Major Description
Running the tests prior to trying to release Wicket 7, I ran into a failure of RepeaterTest:
The component [TransparentWebMarkupContainer [Component id = wicket_extend4]] was rendered already. You can render it only once during a render phase. Class relative path: org.apache.wicket.markup.html.TransparentWebMarkupContainer:wicket_child24:wicket_extend4
MarkupStream: [unknown]

The test case looks like this:
checkPage(tester, RepeatingPage.class);
checkPage(tester, RefreshingPage.class);
checkPage(tester, FormPage.class);
checkPage(tester, SimplePage.class);
checkPage(tester, PagingPage.class);
checkPage(tester, SortingPage.class);
checkPage(tester, OIRPage.class);
checkPage(tester, DataGridPage.class);
checkPage(tester, GridViewPage.class);
checkPage(tester, AjaxDataTablePage.class);
and the test fails with the last checkPage to AjaxDataTablepage.class. When I disable all prior checkPages, the test succeeds. When I try the page in the Wicket Examples, it works.
Checking which pages influence one another:
it appears that running RepeatingPage.class and then AjaxDataTablePage.class triggers this error, while changing the order to AjaxDataTablePage.class and then RepeatingPage.class lets the test succeed.
