Description

When @Inject(optional=true) is applied and the binding isn't available, wicket should skip the injection silently.

To check whether the binding is available, you need to use a try/catch block:
try

{ Binding binding = injector.getBinding(key); // use the binding }

catch (ConfigurationException e)

{ // the binding isn't available }
