BaseWicketTester can't find the pageLink field using reflection when you
override the PageLink class.

Key: WICKET-2030
URL: https://issues.apache.org/jira/browse/WICKET-2030
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4-RC1
Reporter: Maarten Billemont
Currently, BaseWicketTester (line 524) does this:
public <C extends Page> Result isPageLink(String path, Class<C>
expectedPageClass)
{
PageLink<?> pageLink =
(PageLink<?>)getComponentFromLastRenderedPage(path);
try
{
Field iPageLinkField =
pageLink.getClass().getDeclaredField("pageLink");
iPageLinkField.setAccessible(true);
IPageLink iPageLink =
(IPageLink)iPageLinkField.get(pageLink);
return isEqual(expectedPageClass,
iPageLink.getPageIdentity());
}
The problem manifests when you want to customize a page link's onClick by
overriding it like this:
new PageLink<AuthPage>("pageLink", AuthPage.class) {
private static final long serialVersionUID = 1L;
@Override
public void onClick() {
Foo.bar();
super.onClick();
}
});
As a result; the BaseWicketTester tries to look for the pageLink field in the
anonymous class instead of the privately declared pageLink field in the
PageLink class.
BaseWicketTester should either go down the tree:
for(Class type = pageLink.getClass(); type != Object.class; type =
type.getSuperclass())
Or a getter should be made for the pageLink field. (This is what Java wants you
to do).
