Now I have 4 questions : (I've just swithed from 3.2.1 to 3.3.0b2, with python 2.4.4c0 on debian Sid.) 1) TALES root variable -- In a tales expression, where has the root context variable gone? In zope2, we could use path:root/path/to/object or path:/path/to/object, but it doesn't work with Zope 3. How can we access some object with an absolute path? Right, there is not root namespace by default. I actually have never needed this feature. However, you can write your own TALES namespace adapter, so that you can say: mynamespace:root. We sometimes write our own namespace adapters to this sort of thing. 2) utf-8 error in i18nfile -- Why do I always get an error when I try to add some utf-8 text into an i18nfile? I just add an i18nfile in the ZMI, then I chose a name and I set the contentType to text/plain;charset=utf-8. If I enter some text with accents like éàôî, I get a system error which says : UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128). I don't get any error with a simple File object. Okay, I18n file is a demo that is probably not well-developed. Don't use it. I will propose to not distribute it anymore. Noone is using it, so you are on your own finding the problem and providing a patch. 3) order attribute in browser:menuItem directive: --- I want to add a new view tab in the ZMI to be able to edit object attributes of some objects. So I'm adding a new menuItem in the zmi_views menu via ZCML with: browser:menuItem action=properties.html for=.mymodule.IMyClass title=properties menu=zmi_views permission=zope.ManageContent order=2 / (MyClass is just a derived Folder with custom attributes) The problem is: the new tab always appear in the first place. I would like to put it just after the content tab, not before. The order directive does not work for that. How can I reorder the tabs so that my new tab appears in the 2nd position? The default implementation of menus sorts by interface first, and this item is most specific. See zope.app.publisher.browser.menu. If you do not like this behavior, you have to implement your own menu code. In my customer development I am not using the menu code at all anymore. We use viewlets to do everything, including menus. 4) workflow: Where is zope.app.workflow? It has never been released with Zope 3, just as an add-on package. People are now encouraged to use zope.wfmc and zope.app.wfmc. There is also a z3lab extension specifically for document workflows.

If it works for you, so be it, but this is just to warn people that this is a really bad way to make encoding problems go away.

There is also a z3lab extension specifically for document workflows. If you are interested in just fairly simple but understandable workflow, you might want to look at hurry.workflow.
