I usually use something like this:
@Component(parameters = { "page=prop:editEmployeePage", "context=prop:
employee.id })
private PageLink pageLink;
@Inject
private ComponentClassResolver resolver;
@Cached
public String getEditEmployeePage() {
resolver.resolvePageClassNameToPageName(EditEmployeePage.class);
}
