Re: [tlaplus] Difficulties using TLA+ Toolbox


hard to tell what you actually did – the second screenshot shows that TLC is not running but does not indicate any trace of it having run previously.

Attached is the module that you are supposed to write. Create a new model from it, enter "Init1" and "Next1" in the fields "Init" and "Next" of the model overview pane, and hit the green triangle to run TLC. You should see the error described in the hyperbook.

The attempt to break the model at this point doesn't seem to work for me, as I've saved, parsed, recreated the model, and generally done what I can to make it produce an error and been unsuccessful.
