Sure. Maybe a new method is needed which gets tuples of length three which sets value, token and title. Otherwise you can write a subclass of SimpleVocabulary which is more convenient for non-ascii people. (Maybe there is a reason why it is called 'simple' ;-) mac ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] DropdownWidget with SimpleVocabulary causes ConversionError.
I'd like to ask one more question. Why does SimpleVocabulary.fromValues/fromItems() not set 'title' ? Is there any good reason? Current implementation is unconvenient for non-ascii people.

Re: [Zope3-Users] DropdownWidget with SimpleVocabulary causes ConversionError.
Hi, Michael. Your explanations make things very clear. It was my misuse of SimleVocabulary/SimpleTerm. I misunderstood the responsibility of token. I didn't notice that DroopdownWidget renders token only when no title is given. When reading the docstrings of ITerm/ITokenizedTerm/ITitledTokenizedTerm, I couldn't realize such things that you explained. It would be nice that there were a document like your explanation. Thanks a lot.

Hi, Vocabularies hav three levels: value: which is stored in ZODB token: which is used as value attribute of the option tag in HTML-Page. It must be convertable to str with ASCII encoding because when the conversion is done the encoding of the page is not yet known. (Correct me if I'm wrong here) title: which is dislpayed to the user as the contents of the option tag SimpleVocabulary.fromValues uses the values as value, token and title, so it is only useable with ASCII values. So you have to do it like this way: SimpleVocabulary(SimpleTerm(, , ), ...) token might be the uid of value, if it is an object which is stored in ZODB. -- mac ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
