compiled extension code completion

Hi,

I've build a compiled python extension for a Java package using JCC (http://lucene.apache.org/pylucene/jcc/index.html). I can import the extension and use code completion in iPython and PyDev. Unfortunately, Pycharm scans the extension and gives me the following error: "Generation of skeletons for the modules above will be tried again when the modules are updated or a new version of generator is available." Code completion doesn't work in Pycharm.

Best regards,

Christian
