Redmine

I've managed to get Redmine deployed on Oracle 10g / JRuby / Tomcat ok, except when clicking on the "Issues" link the following error is entered to the logs:

ActiveRecord::StatementInvalid (ActiveRecord::ActiveRecordError: ORA-01722: invalid number

    <script>:2

The issue is the* issue_statuses.is_closed='f'* part. is_closed is a boolean 0/1 flag and being accessed as a character. I understand that this query is being generated by Rails? Why would it be doing an = 'f' on this field?

Any help would be appreciated!

Thanks in advance.
