Por necesidades de mi trabajo hemos tenido que crear un portlet que necesitaba seleccionar en las preferencias del portlet una carpeta del Document Library. Buscando y buscando no hemos encontrado ningún código que estuviera «acabado» para usar en un proyecto, así que aquí tenéis como utilizarlo:
En el fichero de «liferay-portlet.xml» hay que configurar la acción para que se puedan guardar las preferencias a partir del fichero config.jsp que creemos.
<?xml version="1.0"?> <!DOCTYPE liferay-portlet-app PUBLIC "-//Liferay//DTD Portlet Application 6.2.0//EN" "http://www.liferay.com/dtd/liferay-portlet-app_6_2_0.dtd"> <liferay-portlet-app> <portlet> <portlet-name>UIB Folder Viewer</portlet-name> <icon>/icon.png</icon> <configuration-action-class>com.liferay.portal.kernel.portlet.DefaultConfigurationAction</configuration-action-class> <instanceable>true</instanceable> <header-portlet-css>/css/main.css</header-portlet-css> <footer-portlet-javascript>/js/main.js</footer-portlet-javascript> <css-class-wrapper>uib-folder-display-portlet</css-class-wrapper> </portlet> <role-mapper> <role-name>administrator</role-name> <role-link>Administrator</role-link> </role-mapper> <role-mapper> <role-name>guest</role-name> <role-link>Guest</role-link> </role-mapper> <role-mapper> <role-name>power-user</role-name> <role-link>Power User</role-link> </role-mapper> <role-mapper> <role-name>user</role-name> <role-link>User</role-link> </role-mapper> </liferay-portlet-app>
