Context reload & Guice

[Uwe Schäfer <sc...@thomas-daily.de>]

Hi list, Hi Al,

i´m fooling around with resin/persistent sessions as well as the new 
DiskPageStore in order to get persistent Page-State after a context reload.
Everything seems to work fine, until Guice comes into play. Application 
as usual:

protected void init() {
Module module = new AbstractModule(){
protected void configure() {
bind(ITest.class).to(TestImpl.class);
}};
addComponentInstantiationListener(new GuiceComponentInjector(this,module));
}
with

public interface ITest { void foo(); }
public class TestImpl implements ITest{ public void foo() { 
System.out.println("foo"); } }
public class HomePage extends WebPage {
@Inject ITest test;
public HomePage(final PageParameters parameters) {
add(new Link("l") {
public void onClick() {
test.foo();
}
});
...

Unfortunately, reinjection of TestImpl fails with:

WicketMessage: Method onLinkClicked of interface 
org.apache.wicket.markup.html.link.ILinkListener targeted at component 
[MarkupContainer [Component id = l, page = org.codesmell.HomePage, path 
= 11:l.HomePage$1, isVisible = true, isVersioned = true]] threw an exception

Root cause:

java.lang.NullPointerException: type
at com.google.inject.util.Objects.nonNull(Objects.java:35)
at com.google.inject.TypeLiteral.<init>(TypeLiteral.java:69)
at 
com.google.inject.TypeLiteral$SimpleTypeLiteral.<init>(TypeLiteral.java:181)

at 
org.apache.wicket.proxy.LazyInitProxyFactory$JdkHandler.invoke(LazyInitProxyFactory.java:412) 


Is this a known problem, or should i file a bug for that ?

Sounds like a bug to me. Could you file a bug for it please?

Anyone? A little diggin shows that the information needed here is not 
supposed to be persisted. Why is that?
