- MLText type is persisted as a Serializable (TODO: investigate alternative storage) - 'nodeService' bean is filtered according to the default locale to provide only String return properties - Go direct to the 'mlAwareNodeService' bean to get access to unfiltered MLText properties - TODO: Proper value searches respecting Locale hierarchy git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@4526 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
