TypeError: can't set attributes of built-in/extension type 'NoneType' in <script> at line number 1

Hi @steve-bate !

I want to try the set of decorators and functions you have developed for jython but, although I have tried lots of things in the last couple of hours, I haven't achieved anything yet. Can you help me? ;-)

This is my development environment:

• openHAB 2.2.0 Build #1112
• EXTRA_JAVA_OPTS="-Xbootclasspath/a:/opt/jython/jython.jar -Dpython.home=/opt/jython -Dpython.path=/etc/openhab2/lib/jython" in "/etc/default/openhab"
• Latest SNAPSHOT version of Experimental Rule Engine installed
• Jython installed at "/opt/jython"
• Your "lib/openhab/ folder is placed under "/etc/openhab2/lib/jython". For example, the "log.py" file is located in "/etc/openhab2/lib/jython/openhab/log.py". I have also chowned the "lib/jython/openhab" folder and the owner of all the files is openhab:openhab.

It seems that everything is correctly setup, but if I create a demo test.py file ("/etc/openhab2/automation/jsr223/test.py") with just the following line:

from openhab.log import logging

I get the error you can see in the title:

2017-12-05 16:44:36.729 [ERROR] [ipt.internal.ScriptEngineManagerImpl] - Error during evaluation of script 'file:/etc/openhab2/automation/jsr223/test.py': TypeError: can't set attributes of built-in/extension type 'NoneType' in <script> at line number 1

Do you have any idea about what's going on? I don't know what else I could try :(

Many many thanks for reading my message and for the code that you have contributed to this repository, it's really great!

Best regards,

Aitor

Hello Aitor,

I haven't seen this error before. Have you tried loading an empty script and seeing if the same error occurs?

Hello Steve!

Thank you for your fast reply 👍

Yeah, I have tried with an empty script file and the log file says that the script has been loaded with no apparent error:

2017-12-06 19:28:50.316 [INFO ] [rt.internal.loader.ScriptFileWatcher] - Loading script 'test.py'

I'm going to start over with the latest stable release of openHAB (2.1.0) and see if things change a little bit. What version of openHAB2 are you using? Because I asume you are using Jython 2.7.0, right?

Thanks for your help and I will report back with my findings!

Hi, have you defined some items?

[bodiroga]

Wow @spacemanspiff2007, that was the problem! ✌️

Everything is working properly now, awesome! Many thanks for your help guys, time to start playing with the rules 👍

Well, @spacemanspiff2007 and @steve-bate , I am not sure this should be closed. I am seeing the same symptom and I have extensive items defined in .items files. Do these have to be otherwise exposed to jython ?

Running a standalone jython 2.7.1 on RPi3. Latest (or near-latest) dev build of OH2 running under Openhabian. (NB the jython 2.7.1 full distro does not install correctly on RPi3 -- fails on setuptools installation). I have following defined in /etc/default/openhab2:

EXTRA_JAVA_OPTS="-Xbootclasspath/a:/home/openhabian/jython2.7.1/jython.jar
-Dpython.home=/etc/openhab2/lib/python/:/etc/openhab2/automation/jsr223/
-Dpython.path=/etc/openhab2/lib/python/:/etc/openhab2/automation/jsr223/
-Djython.path=/etc/openhab2/lib/python/:/etc/openhab2/automation/jsr223/ "
