Link at Lobby to 'Navigator Engineering Part'

Does anyone know how a Link in a lobby element must look like to navigate to the page ‘Engineering Part Navigator’?

Copying the standard-URL does not work when Aurena is configured with language ‘german’.

When changed to english and then copying the Browser-URL to the Lobby-Element the Jump from the Element loads but does not show any data.

Relativ path (whithout the server part in the URL) has the same behaviour.

this does not work:

To start to find the mistage or problem is to understand the URL-Syntax. Can anyone explain the difference?

Important is the <path=> string.

How can I find out what is coded in this string?
