Comments are new so therefor it now appears. There is no option for that (yet). Can you enter a
bugzilla for this?

For now if the comment is a primitive field then you have to subclass
BasicMapper and override this method:
protected Element addCommentElement(EModelElement eModelElement, Element hbmElement) {

and just return null.

You can set your BasicMapper as an Extension.

If the long comment is in a onetomany then the OneToManyMapper has to be extended etc.

Btw, I tested your case before this last release and it worked on mysql.

For my interest how large is the length constraint for the comment?

A comment for a column can be specified with the COMMENT option, up to 255
characters long. (http://dev.mysql.com/doc/refman/5.0/en/create-table.html)

in bugzila:

Okay, I was not aware that there was even a comment length constraint in a db. I will probably add a
comment_max_length option which has default value 0 (=no comment as a default). As comments
apparently can result in low level db errors I prefer to disable it as a default.

I did all what you say, where mistakes?:
......
final ExtensionManager extensionManager = hds.getExtensionManager();
extensionManager.registerExtension(BasicMapper.class.getName (),
BasicMapperEx.class.getName());
extensionManager.registerExtension(OneToManyMapper.class.get Name(),
OneToManyMapperEx.class.getName());
hds.initialize();
......
public class BasicMapperEx extends BasicMapper{

/* (non-Javadoc)
* @see
org.eclipse.emf.teneo.hibernate.mapper.AbstractMapper#addCom mentElement(org.eclipse.emf.ecore.EModelElement,
org.eclipse.emf.teneo.simpledom.Element)
*/
@Override
protected Element addCommentElement(EModelElement modelElement,
Element hbmElement)
{
return null;
}
}
.....
public class OneToManyMapperEx extends OneToManyMapper{
/* (non-Javadoc)
* @see
org.eclipse.emf.teneo.hibernate.mapper.AbstractMapper#addCom mentElement(org.eclipse.emf.ecore.EModelElement,
org.eclipse.emf.teneo.simpledom.Element)
*/
@Override
protected Element addCommentElement(EModelElement modelElement,
Element hbmElement)
{
return null;
}
}

I have comment and haven't table )))

If the comment is on a many-to-one you also have to override the ManyToOneMapper, the same for
ManyToMany.
In the future I will move these utility methods to a separate utility class which can be replaced by
itself. That's easier than overriding all these subclasses.

:) I did what you say:

extensionManager.registerExtension(BasicMapper.class.getName (),
BasicMapperEx.class.getName());
extensionManager.registerExtension(OneToManyMapper.class.get Name(),
OneToManyMapperEx.class.getName());
extensionManager.registerExtension(ManyToOneMapper.class.get Name(),
ManyToOneMapperEx.class.getName());
extensionManager.registerExtension(ManyToManyMapper.class.ge tName(),
ManyToManyMapperEx.class.getName());

I check, extension work (return null from function)..

....

27563 [main] ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate - Unsuccessful:
create table `cstmconditiondocmentstype` (`documentbasetype_e_id` bigint not
null, `linenumber` numeric(2,2), `sublinenumber` varchar(2),

date not null, `conditiondate` date, `saledate` date, `presentingdate` date,

And there is EntityMapper, IdMapper and ManyAttributeMapper. I think it is the EntityMapper as the
error seems to be on the table name.
Hmmm, I see now that your first post already mentioned this, I should have looked better...
