During dev mode (gwt 2.5.1), gwt complaints in the gwt dev mode console
about a compiler error, mainly:
This error I don't see in Eclipse, using java 1.6.35.
00:00:55,152 [ERROR] Line 45: Bound mismatch: The generic method
> createSimpleCheckTracker(FormField<SelectedBooleans>, W, H, N, Form, P,
> AsyncConfirmer) of type FormFieldMutationFacade is not applicable for the
> arguments (FormField<SelectedBooleans>, W, H, N, Form, null, null). The
> inferred type HasSize is not a valid substitute for the bounded parameter
> <P extends HasSize & HasIndexOf<IsWidget> & HasRemoveAllStart>
Line 45 is the forward of the first method below to the second method. The
error concerns the fore last argument which is null (the P generics)...
Any idea why their is a difference in compiler output ?
The code:
public <W extends HasWidgetRead, P extends HasSize & HasIndexOf<IsWidget> &
> HasRemoveAllStart, H extends HasFlexWidget<W>, N extends HasNextBoolean>
> ValueChangeFormFieldTracker<SelectedBooleans> createSimpleCheckTracker(final
> FormField<SelectedBooleans> formField, final W widget, final H hasWidget,
> final N nextProcessor, final Form form) {
> return createSimpleCheckTracker(formField, widget, hasWidget,
> nextProcessor, form, null, null);
> }
>
> public <W extends HasWidgetRead, P extends HasSize & HasIndexOf<IsWidget>
> & HasRemoveAllStart, H extends HasFlexWidget<W>, N extends HasNextBoolean>
> ValueChangeFormFieldTracker<SelectedBooleans> createSimpleCheckTracker(final
> FormField<SelectedBooleans> formField, final W widget, final H hasWidget,
> final N nextProcessor, final Form form, final P container, final
> AsyncConfirmer confirmPerformer) {
>
....
> return .....
}
