Hello,

I didn't find anything about it in the forum nor in the docs: is it possible to persist a 2d-array like
[quote]Cat[][] catArray;[/quote]?
I know it works with
[quote]<property name="catArray" type="serializable">[/quote]
This requires Cat being serializable. Is there any other way?

Or is there a way to persist it like an array with
[quote]
<array name="catArray">
<key column="holder"/>
<index column="position"/>
<many-to-many class="Cat"/>
</array>
[/quote]?
If the index (position-column) would hold tuples like (1, 1) (1, 2) instead of simple integers, this could work, couldn't it?

Thanks,
Alice

Try to consider your 2d-array as a collection of collections, this can help

No this can not help.

I don't know of any really good way to map this. Rethink your data structure probably.

Thanks for the answer.
Unfortunately I can't rethink my data structure - it's legacy data. So it will have to work with serialization. Are 2d-arrays that rare (no mapping tool I know supports multidimensional arrays)?
Does it mean lots of work to alter the array-index element in the mapping file so that it can manage tuples?
Have a nice day,
Alice
