I am working on a ETL rule that creates elements on an output model that already has some elements on it. Some of the existent elements and the new ones need a consecutive id number, so I need to collect all the elements of type IdElement to get a list of existing ids and use the next one. My problem seems that I can not access the existent elements of the output model. I use read on load and store on disposal and new elements are indeed created. Any idea on how to access existent elements?

Thanks,

Hi Horacio,

If your target model is named Target, you should be able to get all
elements of type IdElement using Target!IdElement.all. What does
Target!IdElement.all.println() print?

Cheers,
Dimitris
