Hi,

is there any documentation how to create lists instead of sets for 1:n relations? Currently the hibernate tools create (Hash)sets, which would need more effort to sort. I saw that there are hbm templates for list, how can I use them? I tried to replace the content of set.hbm.ftl with the list, but that caused an error. I think there's some logic in the classes for reverse engineering to control that.

I think I know how to manually do that, but I have ~20-30 tables, and I would also have to change the java part, which currently uses sets, too.

Can't imagine, that these template files are without any usage included for two years or more, so..help me please :)

When you replace the code in template you should take into account that in Set.ftl property's value has org.hibernate.mapping.Set class, but in list org.hibernate.mapping.List. So you must change the template so it call only existing method from the value. For example Set class hasn't methods get/setBaseIndex, get/setIndex...

Nowise without changes.
But you could remove all wrong method calles and use "truncated" version of list template.
