[tlaplus] Issues with seeing error trace and enabling Deadlock setting
Hi folks. To get started, I'm tried running the basic example from https://learntla.com/introduction/example/.
---- MODULE example ----
EXTENDS Naturals, TLC
(* --algorithm transfer
variables alice_account = 10, bob_account = 10, money \in 1..20;
A: alice_account := alice_account - money;
B: bob_account := bob_account + money;
C: assert alice_account >= 0;
end algorithm *)
Save that to `example.tla`, compile the PlusCal to TLA+, create an empty model and run that model. I do see a similar error but I don't see any error trace as shown in the screenshot here: https://imgur.com/a/AzCEe0a.
Is it because of some misconfiguration? Any suggestions for debugging?
Configuration information: Ubuntu 20.04 LTS, v1.7.0 Aristotle zip from https://github.com/tlaplus/tlaplus/releases/, running javac/JDK 14.0.1.
As an alternative, I did try v1.6.0 Zenobius and that does show the error trace OK, so I'm going to use that for now.
I also noticed that the "Deadlock" box on the Model Overview screen is unchecked by default
(and clicking it does nothing), unlike the macOS screenshot on learntla.com.
However, I can add/select/unselect Invariants and Properties just fine. This problem seems to be present with both v1.6.0 and v1.7.0.
