Hi,
I noticed that product page aliases translated in Falang were ignored by J2Commerce routing, so I created a plugin to address this
It reads translated product aliases from Falang and uses them when generating J2Commerce product URLs on the frontend. It also resolves incoming translated product aliases back to the original J2Commerce product, preventing 404 errors when visitors open localized product links directly.
The plugin does not modify Joomla core, Falang, com_content, or J2Commerce. It only adds a compatibility layer for multilingual J2Commerce product routing.
