Ladies and gentlemen, Some time ago I wrote to the list to ask for help on a product reloading issue. I'm still banging my head against it now, so i'm restating the problem again in the hope someone can help: I have a very simple product (and it works!) Any changes I make don't get reflected in the product, so... 1) I change the function name in order to break it on purpose 2) I stop and restart Zope (or use the refresh product) ...and... 3) Zope thinks the product still works ?!?!£?"$"" This behaviour exhibits itself in Zope 2.1.6 *and* 2.2.0. Since no-one else ever seems to have had this problem, I can only assume I am doing something wrong at a "doh!" basic level. Sounds to me like the product is getting cached in the ZOBD. I'm only a poor newbie, so I don't really know where to go from here in order to debug the problem. Any clues???? Thanks, Seb.
