Set field appears frozen
I have a relationship: Patient < Calc < Prescription with portals on Patient layout for Calc and Prescription. There's a select button in Calc portal, so that when a 'calc' is selected, only the related precriptions populate the Prescription portal:
Set field[Patient::Calc_n; Calc::CalcID]
However, this only works for the first Calc record; it won't change if I add more. I can see this because the Patient::Calc_n changes when I select different Calc record in the portal, but Calc::CalcID remains the same.
