help Zend_Registry drops key lang out - zend-framework

Question

can't figure out, why does key lang disappears between language plugin and matched custom route. I'm calling registry from inside model, which is requested inside custome route.

I have checked inside language plugin, it registers lang key fine.
Zend_Registry::get('lang') inside route throws exception as well.

Make sure the Registry-Key is set in Plugins_LangSelector::routeStartup() so it will be registered before processing the routes.
From the ZF-Manual: Plugins
routeStartup() is called before Zend_Controller_Front calls on the router to evaluate the request against the registered routes.
If you set the key in routeShutdown(), preDispatch(), postDispatch() or dispatchLoopShutdown() it is to late.
