Please always use pastebin.com or paste.kde.org to show your codes instead
of putting them in emails.

I think it= s ok to paste in a mail if its a snippet not too long, because it helps other people who will later read the ML archives, as pastebins may expire.

So that function it's calling, views.analyzeviews(arg, arg) is call= ing a web API and sometimes that API fails.=A0 The cool thing about data en= gines vs when I used to do this on the commandline is that if it fails at 2= 5, it doesn't crash the whole program.=A0 It just moves on to 50.=A0 So= I can end up in the end where when I click on 25 it tells me that there= 9;s nothing in the source and then I click on 50 and I can use the data fro= m that source.=A0 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&#= 39;t fail that time around.=A0 Is there a way for me to tell the data engin= e to update group 25 again from within the QML gui?

Thanks!
