The simplest solution is to use:
#mountPage("/products/#{category}/#{product}", ProductsEntryPage.class);
class ProductsEntryPage extends WebPage {
public ProductsEntryPage(PageParameters params) {
category = params.get("category")
product = params.get("product")
WebPage toRender;
if (hasCategory(category)) {
if (hasProduct(product)) {
toRender = new ProductPage(category, product);
}
else {
toRender = new CategoryPage(category);
}
}
else {
toRender = new ProductListPage();
}
throw new RestartResponseException(toRender);
}
}
