Yo, I installed ZGDChart and was playing around with it. cool stuff... But I came across this problem: at first, everything worked fine, but know, whenever I try to view a chart, my zope server restarts. no messages what so ever. I tried the test.py that came with ZGDChart , and that seems to work fine. I don't have a clue on how to tackle this problem except for adding print 'cucu' lines all over the ZGDChart code :( I have a 2.4.0b3 built from source and a 2.1 python (if this might help) Anyone any ideas ?? TIA, Sloot.
