The fix for this is to delete the index (workspace and archive folders under alf_data/solr4/index) and restart the server. Go get lunch it will take awhile if you have many docs in the repository.
As best I could decipher from the Jira about the enterprise fix is that the indexes were being created before the models were being integrated into the solr ??
Just installed Community 5.0b and no categories are displaying while browsing the document library, nor are they available from the admin category-manager or create rules form. Error in logs when you try to add a category to the root is
Caused by: org.alfresco.error.AlfrescoRuntimeException: 09200035 Missing classification: {http://www.alfresco.org/model/content/1.0}generalclassifiable at org.alfresco.repo.search.impl.lucene.LuceneCategoryServiceImpl.createRootCategory(LuceneCategoryServiceImpl.java:510)
The default classifications are present (I can see them with the node browser). SOLR4 issue or I screwed up the install?
