TYPO3 Core

It seems to be not possible to link from one BE module template to an action of another extension using the <f:link.action ViewHelper.
The Viewhelper documentation states, that this should be possible when adressing action, controller, extensionName and plugin attributes.

The following code will render only the plain text without linking it.

<f:link.action action="list" controller="MyController" extensionName="myotherextension" pluginName="myotherextension_mycontroller" >
    link to another extension controller action
</f:link.action>

It seems that somewhere in \TYPO3\CMS\Extbase\Mvc\Web\Routing\UriBuilder::buildBackendUri the routeIdentifier gets taken from the request object. So from the first extension. That way it cannot create a route to the second extension.

A workaround seems to be to add the route as an argument like

<f:link.action action="list" controller="MyController" extensionName="myotherextension" pluginName="myotherextension_mycontroller" 
  arguments="{route: 'myotherextension_mycontroller.MyController_list'}">
    link to another extension controller action
</f:link.action>

But that does not seem to be the right way and does not follow the documentation.
Do I miss something?
