- SOLR tracking now reflects all models loaded and changed on the repo to which it points - model tracking and related fixes - model XML now round trips for Boolean properties :-) - upgraded to latest version of jibx - 1.2.3 - added API to load models and not class load constraint extensions (does not affect the generated model XML only constraint enforcement) - removed solr specific m2 model binding - fixed SOLR tracking test git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@28714 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
