I'm in the process of porting an application from LV 8.2 to LV 8.2 PDA. The application relies
heavily on using the controls[] property node which I just found out is not
supported in LV 8.2 PDA. Does anyone know of any alternative method of
extracting a cluster's controls array without using a property node?
Currently, there is now way to obtain a reference to a control inside a cluster in LV PDA. I have experimented a great deal with alternatives, but to no avail. However, I think you you may be able to accomplish the same behavior using just an unbundle, or just using explicit controls outside of a cluster. Hopefully we will have that functionality in a future version of LabVIEW PDA.
I've spent quite a lot of time trying to find an alternative without any luck. Without full property node support, there is no other option other than manual cluster interactions.
