Re: How to use a mounted shared resource as a link resource?

[Robin Sander <ro...@gmx.net>]

To answer my own question in case anybody else has a similiar problem:

There's a urlFor(ResourceReference) method in Component, so store the  
ResourceReference
in the application, then access it in the Component which needs the  
URL and call urlFor().
