Custom interval fields

109

I’ve a (public) custom interval field VE-EF that generally works fine, but does not fill upon original loading of the file, only after manually reprocessing the file again.

I have “process fit file messages” selected. The javascript is as follows:

{
  interval.average_tidal_volume_min > 0 ? 
    interval.average_watts / interval.average_tidal_volume_min : 
    undefined
}

Any idea what’s going on here and how to fix it – such that it computes and displays the intervals on original load and when defining additional intervals with the mouse cursor?

The field has another “funny behavior” as in that it does not show a description in the list of fields despite me having defined a description in the definition of the field…
