Hi Kay,
The reason of refreshing BOY OPI dynamically is I found that BOY runtime OPI can not update my C# type EPICS PV's access rights.
For example, 1) if the PV' access right is r+w, run the OPI and it can change the PV's value using 'Text Input' widget; 2)if the PV's access right is readonly, run the OPI and re-change PV's access right to r+w, PV's value can not be changed using 'Text Input' unless refresh OPI once.
