Internationalization of e-commerce products
I want that one product could have one stock and different descriptions.
You have to setup your primary language, then create additional pages for each language.
Here is a link to an education I did that covers working with the Internationalization Add-on in Concrete5:
I hope this helps you work toward a solution.
"Content" translation is not automatic. You will need to utilize multi-lingual staff to physically translate or trust something like Google Translate to do the task. We are currently trying to use both... Copy/Paste Google translated content then have a native speaker proof read it to correct sentence structure etc. to save money on having translation done from scratch. The Market-Place has a couple of Google based Translate add-ons for free but don't achieve the end result we're looking for.
(by the way, does your eCommerce product list block work with International installed?)
Just remembered eCommerce is not duplicated in the different language trees. My initial advice to you is therefore useless :(
As I'm working on a similar project, please share any solution you come up with and I'll be sure to do the same.
