Hello! (Nobody dared to answer, retrying...) I started to learn ZClasses. I created a product, added a Zclass in it, and added a Zcalss inside outer ZClass - I want to create ZClass that's addable only inside outer ZClass. Then the problems begin. All management URLs for inner ZClass contain %20, so URLs look like "propertysheets/methods/RandomZItem%20/manage_workspace" and "propertysheets/methods/RandomZItem_add%20/manage_workspace". If I click on the link I got the AttributeError (of course). When I manually remove the offending %20, I can manage the object, but it's tiresome to remove it every time. The problem manifested on both 2.1.4 and 2.2.0b3. What's wrong? Oleg.
