@eguiraud thank you very much on taking the time to troubleshoot. Looks like this is the bottleneck for using RDF on my work; however, changing to int or unsigned int is not so trivial… (I reckon). I will need to refer to my colleague on the root file regeneration with the suggestion though.
On the other hand, it would be great if this is included in the future release.
I am open to other opinion if there is a mini-hack to get through it though.
Looking forward to hear from you all!
Cheers,
Siewyan
