In our own, old ORM library we could set additional field NUMBERID in join tabe for relations many-to-many to keep elements order.
The sorting was processed implicitly. It was possible to insert, add and delete items in necessary positions.
There are some possibilities to realise this property in OpenAccess ?

Hi Igor,
Are you using the Classic approach or the Context (Visual Designer) approach?
I know it s possible with the Classic one, exactly the same way by selecting "Ordered" on the m:n relation.

Henrik

Hello Henrik,
Henrik is correct; there is a similar functionality in the OpenAccess ORM Classic wizards. A property is made available for this purpose, called Preserve Order. You can find a detailed description here.
As for the Visual Designer, unfortunately this functionality is not directly available on the association options screen. Basically, there are two options:
1) You can add manually your additional field in the SequenceColumn of the MetaJoinTableAssociation object.
2) You can use the Fluent Mapping API for your mapping as a general approach. We recommend it in case you have other complications in your model and you would like to have a better handling of the low level operations like this one. Here you can find the explanation of using SequenceColumns with the Fluent Mapping API.
Let us know if you would like further assistance or advice on this – whichever option you choose.
Kind regards,

Hi Ivailo,
Thanks for pointing it out. It was "Preserve Order" and not "Ordered"... typo :-(
