Hey,
So this is interesting. The Compiler decided not to compile one of my
classes. So at runtime I get the wonderful ClassNotFound exception.
There are no errors, everything succeeds. No idea how to fix it, and
it's very weird. Here's the setup...
@Singleton
public class LandingPagePresenterImpl implements LandingPagePresenter
{
LandingPageDisplayProvider landingPageDisplayProvider;
...
@Inject
public LandingPagePresenterImpl(LandingPageDisplayProvider
landingPageDisplayProvider, ... ){
this.landingPageDisplayProvider = landingPageDisplayProvider;
...
}
...
@Override
public void onAtLandingPage(AtLandingPage place) {
...
// setup child presenters
setLoginPresenter(loginPresenterProvider.get());
...
setDisplay(constructDisplay());
...
}
public LandingPageDisplay constructDisplay() {
LoginDisplay loginDisplay = (LoginDisplay) getLoginPresenter
().display();
return landingPagedisplayProvider.get(loginDisplay);
<<<<<------- CODE FAILS HERE! (ClassNotFound)
}
}
The provider looks like so...
@Singleton
public class LandingPageDisplayProvider implements
Provider<LandingPageDisplay> {
/* dependencies */
private LandingPageBinder binder;
@Inject
public LandingPageDisplayProvider(LandingPageBinder binder) {
this.binder = binder;
}
@Override
public LandingPageDisplay get() {
return null;
}
public LandingPageDisplay get(LoginDisplay loginDisplay) {
return new LandingPageDisplayImpl(binder, loginDisplay);
}
}
within my Module I have
bind(LandingPageDisplay.class).toProvider
(LandingPageDisplayProvider.class);
For good measure here is the display impl
public class LandingPageDisplayImpl extends Composite implements
LandingPageDisplay {
public interface LandingPageBinder extends
UiBinder<DockLayoutPanel, LandingPageDisplayImpl> {
}
private LandingPageBinder binder;
@UiField(provided = true)
LoginDisplayImpl loginDisplay;
public LandingPageDisplayImpl(LandingPageBinder binder, LoginDisplay
loginDisplay) {
this.binder = binder;
this.loginDisplay = (LoginDisplayImpl) loginDisplay;
initWidget(this.binder.createAndBindUi(this));
}
}
So, one, I think its an MVP compatible way of using UiBinder and GIN.
And two, it's not working :). I should mention that LoginDisplay
doesn't have any issues as it is just a Label, so it doesn't have any
UiField annotations.
When I compile.. I look at SOYC and LandingPageDisplayImpl is
there!!
In SOYC my compiled display package looks like this:
package.LandingPageDisplayImpl
package.LoginDisplayImpl
package.LoginDisplayImpl_LoginDisplayBinderImpl (the binder
implementation that GIN automatically injects by calling GWT.create)
So, from SOYC it seems that LandingPageDisplayBinderImpl is missing.
But when I step through Debug code it says LandingPageDisplayImpl is
missing (ClassNotFound exception).
Does anyone have an idea where to start???
