Hi,
I'm looking for something that should be supported out of the box, or just can be very easy to implement, because it is the most common use case for a Document Management System that I can think for

I'd like to write in a property (defined in a custom type or in a custom aspect) on node creation containing the max()+1 of its kind.
For example, if I insert a document of type X (or specialize an existing document) I'd like to have x.progressiveId = (number of documents of type X)+1 and the property should be unique.

Better, if I can put a partition value (for instance, the max()+1 should be implemented taking in account another property, for instance a property "year" so that 1st of January we can start again from 1)

Are there tutorials/best practices I can follow?

I've a rough idea of the path to implement it (use behaviors/store the current max() value in a node with known id) but if there is something 'ready' i would be much happier!

thanks to everyone
