ValueError: '0' is not in list

When running lantz sims fungen tcp, I get the following error:

Traceback (most recent call last):
  File "/Users/wheelerj/miniconda3/lib/python3.6/site-packages/lantz/qt/widgets/common.py", line 162, in on_feat_value_changed

    self.setCurrentIndex(self.__values.index(value))
ValueError: '0' is not in list

It works when I run lantz sims voltmeter tcp, however it crashes the moment I try to change one of the values.

I was not able to reproduce these. Can you try with the version on github?

[jondoesntgit]

I get the same error with the same version on Github. I'm using python 3.6 on MacOS Mojave.

[hgrecco]

Ahh. The qtpanel crashes, not the simulator. right?

[jondoesntgit]

That is correct.

[hgrecco]

Please update to pimpmyclass 0.4.2 with pip install -U pimpmyclass and try again.

Just for the record: recently we (re)enabled bidirectional sync between the Qt Gui and a Driver (which was disabled temporarily while migrating to pimpmyclass). This was broken for Mapping Feats (i.e. those using a dict in values.

Recently pimpmyclass was refactored to allow Config and InstanceConfig, and additionally a better notification for get and set was added.

[jondoesntgit]

Upgraded from pimpmyclass 0.3 to pimpmyclass 0.4.2

[hgrecco]

Can you update lantz again from the github version and try again?

[jondoesntgit]

I had to run this to make it work

$ sudo pip uninstall lantz-core

Successfully uninstalled lantz-core-0.5

$ sudo -H pip install git+http://github.com/lantzproject/lantz-core

Successfully installed lantz-core-0.5.1.dev0

[hgrecco]

Then it works, right? I will be releasing the next version soon.

[hgrecco]

0.5.2 version of all packages was released
