So that function it's calling, views.analyzeviews(arg, arg) is calling a web API and sometimes that API fails. The cool thing about data engines vs when I used to do this on the commandline is that if it fails at 25, it doesn't crash the whole program. It just moves on to 50. So I can end up in the end where when I click on 25 it tells me that there's nothing in the source and then I click on 50 and I can use the data from that source. So, right now if I want the data from 25, the only way I know how to do that is by re-running the program and hoping the API doesn't fail that time around. Is there a way for me to tell the data engine to update group 25 again from within the QML gui?
Thanks!
