did you try to run this script for updating a 3.1 database to a 3.2 database? I'm looking into this, but afaik, this is for creating a new database (even if one already exists). I did it several times and did not encounter these errors. It's simple, if the fk's are not deleted, you cannot drop the tables..... that is mysql behaviour. Then do a truncate first or something delete the schema and create it again... not so difficult, is it? I've worked with mysql and jbpm for 4 years now... you have to be a little creative, but just a little. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4032192#...
