Getting ...WithUserSpecifiedFieldOkay_33_g$(...).style_86_g$ is not a function when injecting child view

[Stefan Falk]

I am sorry to bother you guys with so many questions but I'm having a hard time to getting warm with GWTP..

My problem [1] is that I want to add a modal to a parent presenter. It's just wrapping an already functional modal for me but for some reason if I add OfferModalView offerModalView to the constructor:

@Inject
CalendarView(Binder uiBinder, OfferModalView offerModalView) {
    this.initWidget(uiBinder.createAndBindUi(this));
}

- where CalendarView is basically the parent view - then I am getting this error:

Caused by: com.google.gwt.core.client.JavaScriptException: (TypeError) : 
           this.get_clientBundleFieldNameUnlikelyToCollideWithUserSpecifiedFieldOkay_33_g$(...).style_86_g$ is not a function

I have no idea what's wrong. I used the GWTP Eclipse Plugin to create this PresenterWidget and said it should be bound as Singleton.

Could somebody help me with this?

It appears that myProvider.get() is the root of this exception:

for(int i = 0; i < 7; i++) {

LOGGER.fine("Adding day " + days[i]);

// Causes the exception:

DayCollapsiblePresenter dayCollapsiblePresenter = this.dayCollapsiblePresenterProvider.get();

// Does not reach this line ..

dayCollapsiblePresenter.setDay(days[i]);

this.addToSlot(SLOT_DayCollapsibles, dayCollapsiblePresenter);
