There's a few things off with the code you pasted that may be throwing
assistedinject off.
The factory interface should just be:
* interface Factory {*
* Baz create(@Assisted("foo") Long p1, @Assisted("bar") Long p2);*
* }*
.. that is, no @Named(..) binding on the 'create' method.
Additionally, you added that you're expecting to have bindings like:
*
bind(Long.class).annotatedWith(Assisted.class).toInstance(System.nanoTime());
bind(Long.class).annotatedWith(Assisted.class).toInstance(4L); *
... but you actually _shouldn't_ have those bindings. AssistedInject
creates the assisted bindings for you automatically when you install the
module & call the factory methods.
Are you certain that TestowaRodzinaWładysława is injecting the factory (as
opposed to injecting the assisted object (Władysław) & calling create on
the factory? The error looks like what would happen if you attempted to
inject the assisted object directly.
