Auto-complete stops displaying keywords from Python libraries

[wdomes]

Sometimes, keywords from installed Python libraries (e.g. selenium2library, BuiltIn, etc.) stop displaying in the auto-complete menu in PyCharm. User defined keywords continue to display in the auto-complete menu. I've been able to get the keywords to display again by "refreshing" the Python instance in PyCharm with these steps:

1. In Preferences -> Project: -> Project Interpreter, change the Project Interpreter to a different Python instance/installation.
2. Click Apply.
3. Change the Project Interpreter back to the previously selected Python instance/installation.
4. Verify the expected installed Python packages display in the Preferences window.
5. Click OK.

I've noticed that PyCharm shows a Null Pointer Exception coming from the plug-in regarding the auto-complete, but I can't tell if it is related to the library keywords not displaying. Here's the exception from PyCharm:

I'm running Mac OS X 10.10.4, Java 1.7.0_75-b13, PyCharm 4.5.3, Python 2.7.6.

The Python Robot Framework libraries I have installed are: robotframework (2.8.6) robotframework-appiumlibrary (1.2.3) robotframework-databaselibrary (0.6) robotframework-selenium2library (1.5.0)

Sorry for the very embarrassing delay of my answer :-/

Anyway, does it still happen with the new versions of the plugin? can you please tell me the affected version of the Robot Framework Support plugin?

Thanks,
