Even the apply machine is empty when I do an xml=T

The apply list will show in the XML if: 1. View mode and the record is already saved with something applied. 2. Edit mode and there is something applied/available to apply.

Yeah, I agree with your point, so here is the thing: if you see in the previous screenshot, there are filters in there that I enabled for this sublist as it was a long one. Now, if you filter something on that sublist in ui and do a record load in the script, this does not bring any result. So, I have to clear the filter first. Weird thing, but Yes, that was it.
