Verifying a parameterized property yields Runtime Exception

Hello

I have a model and I want to check some properties (model attached).

NeverZone(z) == [] (sigma[varloc["PId"]] # { z  }
NeverZ3 == [] (sigma[varloc["PId"]] # {"f3”})

In the toolbox, when I check NeverZ3 (in properties) it works (the model verifies the property). However, when I check NeverZone(“f3”) I get:

TLC threw an unexpected exception.
This was probably caused by an error in the spec or model.
See the User Output or TLC Console for clues to what happened.
The exception was a java.lang.RuntimeException
: 
In evaluation, the identifier sigma is either undefined or not an operator.
line 15, col 43 to line 15, col 47 of module PWSSemantics

(I ended up with this error trying to find the cause of another same message on sigma being erroneous)

With #317 fixed, TLC now reports the following for this spec:
