-----------------------------------
> This should probably not be fixed in DbEntity, but in the DropColumnToModel
> token. I will take a look at it.
So I would then have to create a DromColumnToModel object to perfrom an
operation as below...?
if (!hasFooColumn())
{
DbEntity db=dataMap.getDbEntity("YYYY");
db.removeAttribute("acolumn");
}
> ObjRelationsship's are not removed processing DropColumnToModel
