Liferay. Please enter a valid XML URL.

После инсталляции Liferay (в моем случае 6.1.10EE) при попытке добавить новую страницу (Site Pages -> Add Page) вылезает сообщение "Please enter a valid XML URL."

В моем случае лечится так: заходим в Control Panel -> Porta -> Portal Settings -> Display Settings, проверям, что язык по умолчанию "English (United Kingdom)" и жмем Save. Пробуем добавить страницу еще раз.

mvn versions:display-dependency-updates

Познакомился с Versions Maven Plugin.

А вообще на домашней страничке много чего еще интересного. Но пока только эту команду попрактиковал.

Концфигурация rebel.xml для Liferay Theme.

Инициализация новых объектов в Velocity. Liferay.

В Liferay (6.1.1) возникла проблема с отображением подменю в навигации, если страница является скрытой (hidden). Дело в том, что эта страница не попадает в массив элементов $nav_items, доступный в шаблоне (velocity, в данном случае).

Некоторое время траха поисков привели к такому варианту:

#set($layoutLocalService = $serviceLocator.findService("com.liferay.portal.service.LayoutLocalService"))

#set($longClass = $portal.getClass().forName("java.lang.Long"))
#set($longClassPrimitive = $longClass.getDeclaredField("TYPE").get(null))
#set($httpServletRequestClass = $portal.getClass().forName("javax.servlet.http.HttpServletRequest"))
#set($themeDisplayClass = $portal.getClass().forName("com.liferay.portal.theme.ThemeDisplay"))
#set($requestVarsClass = $portal.getClass().forName("com.liferay.portal.theme.RequestVars"))
#set($navItemClass = $portal.getClass().forName("com.liferay.portal.theme.NavItem"))
#set($layoutClass = $portal.getClass().forName("com.liferay.portal.model.Layout"))

#set($requestVars = $requestVarsClass.getConstructor($httpServletRequestClass, $themeDisplayClass, $longClassPrimitive, $longClassPrimitive).newInstance($request, $themeDisplay, $layout.getAncestorPlid(), $layout.getAncestorLayoutId()))

#set($ancessorLayout = $layoutLocalService.getLayout($layout.getAncestorPlid()))
#set($currentNavItem = $navItemClass.getConstructor($requestVarsClass, $layoutClass).newInstance($requestVars, $ancessorLayout ))

работает на ура.
