Unable to set Availability of Output attribute

Environment
Python package 3.0.0 (also tested on 3.0.2)
OpenTAP 9.19.4

Details

See attached files to recreate. I am trying to create a parent step with an output property connect to its own child step with an input property. When either parent step is run, a deadlock error is generated.

There are two versions, with input type Double and input type OpenTap.Input[Double].

Ok, after checking it out.

The problem is that output availability needs to be used as a named argument and not as a positional one.

Instead of this:
outputProp = property(Double, 0.0).add_attribute(OpenTap.Output(OpenTap.OutputAvailability.BeforeRun))

do this:

outputProp = property(Double, 0.0).add_attribute(OpenTap.Output(availability = OpenTap.OutputAvailability.BeforeRun))

A minor change is also that ChildTest needs to use f"{self.inputProp}" and not f"{self.inputProp.Value}" in this case.

So the 'workaround' is to use a named argument.

This needs to be fixed inside PythonNet, since it does not handle named/positional arguments correctly in this case. It should accept either version of the code if possible.

That works, thanks for the workaround
