I think it will be easiest to explain the problem I am seeing with an example:
I insert a LabVIEW action step, and specify the module to be an express vi (Create Histogram Express vi). I am trying to assign an expression to one of the elements inside the Waveform Array that is returned. For example, assigning dt of Element1[0] to a local variable. After this, if I try to configure the express vi, and then open the specify module dialog, the local variable assignment expression disappears.
Is this a bug or am I not performing a valid operation?
Thanks.
