Hi, I have the Zope 2.7.0 instaled under Linux OS. I want to have my website in many languages in one Plone site. So I have installed "Placeless Translation Service". I've made 2 .po files (cms_pl.po, cms_en.po) and compiled to .mo files (cms_pl.mo, cms_en.mo). I want to change website language version based on varriable value in ZPT and this is the problem (I think). When I do .po files with the same domain, e.g: "Domain: CMS\n" and they have different "Language-Code:" header e.g: "Language-Code: pl\n" and "Language-Code: en\n" Zope chooses language based on web browser settings :(. When I'm setting "xml:lang" and "lang" attributtes it doesen't make effect. There is second way. I can do 2 .po files with different "Domain" and choose the one depends on variable but I cant dynamicialy set "i18n:domain" attribute. How to manage that? Thanks in advance Krzysztof Kubacki
