Paolo,
I looked into this and the issue is caused because we don’t offer context help for any tags that have been deprecated. In the xtags file the following fields are flagged as deprecated:
jboss.column-name, jboss.read-only, jboss.jdbc-type and jboss.sql-type. Instead, you should be using ‘ejb.persistence column-name’, ‘jboss.persistence read-only’, ‘ejb.persistence jdbc-type’ and ‘ejb.persistence sql-type’, respectively.
