help Zend_Registry drops key lang out

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') ins开发者_如何转开发ide 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.
