Great! That was my solution: use the 'id' property.
Could I expect to have the same ("char_init_id" generated) Id for the 
same objects every time that I run the engine?

That was a good solution too. But in this case my previous question is 
negative: I allways will have different numbers, and I don't know how to 
iterate between the items to have an ordered list...



Thank you all again for your answers!
