I'm just moved from xdoclet 1.2.2 to 1.2.3 and am now getting an error generating my hibernate hbm.xml files. Did not find this covered elsewhere.

Thank you for any suggestions - Richard

Hibernate version: 2.1.8 or 3.0.5

Mapping documents:

Below is the markup in my classes followed by the the exception and stack trace from my ant build. Note that the many-to-one tag that is generated for my "status" property ends up with two instances of the attribute/keyword 'unique="false"'.

Is this a bug or do I just need to change my configuration somehow?

Thank you - Richard

Name and version of the database you are using:MySQL 4.1.7

The generated SQL (show_sql=true):N/A

Debug level Hibernate log excerpt:N/A

Turns out this is a bug. I loosened up my search criteria and found that this is already a reported bug:

http://opensource.atlassian.com/projects/xdoclet/browse/XDT-1349

However the fix is applied to version 1.3 which is not yet stable, at least for my purposes (from my quick experience documented below).

The good news is that the fix only involved commenting out 3 lines in hibernate-properties.XDt (see the problem report above for details).

All is well, isn't open source a great thing :)
