<div>Hi all,</div><div><br></div><div>I'm running into an odd issue with the ReckonPrimer Activity some Austrian students have developed for our pilot project.</div><div><br></div><div>Starting the activity works fine on just about every software version I've tried but unfortunately fails on build 767 which is the one being used in the school at the moment (yes, I'm well aware that's quite outdated hence why I'm looking forward to 11.2.0 and its German support;-).</div>
<div><br></div><div>In the log it says "IOError: [Errno 13] Permission denied: '/home/olpc/Activities/ReckonPrimer.activity/data/Collection.data'" (for the complete log please see the end of this e-mail) whereby the offending function is in collection.py (.xo file available at <a href="http://derndorfer.eu/files/permanent/ReckonPrimer-7.xo" target="_blank">http://derndorfer.eu/files/permanent/ReckonPrimer-7.xo</a>):</div>
<div><br></div><div><div> def set_data_in_pickle(self, root):</div><div> """ Sets data in pickle file """</div><div> path = os.path.join(os.getcwd(), "data/Collection.data")</div>
<div> f = open(path, "wb")</div><div> pickle.dump(root, f)</div><div> f.close()</div></div><div><br></div><div>I really don't understand why this causes issues in 767 but none of the other (newer) software versions and I'd appreciate any pointers, thoughts or advice here. :-)</div>
