In our app, we have a UiBinder widget (SomeViewImpl) which has, as its root
element, a widget which itself is a UiBinder widget
(CollectionManagementLayout).
My UiBinder declaration in SomeViewImpl looks like this:
interface CollectionManagementPanelUiBinder extends
UiBinder<CollectionManagementLayout, SomeViewImpl> {}
The UiBinder XML for the SomeViewImpl class starts off like this:
<collectionmanagement:CollectionManagementLayout ui:field="layout">
. . .
</collectionmanagement:CollectionManagementLayout>
This code compiles just fine in GWT 2.7, but with 2.8, I get the following
error:
[ERROR] Errors in
'generated://09CDEAB17C92C8C75AB00C9F2F0DF847/com/myco/myproduct/client/stuff/collections/SomeViewImpl_CollectionManagementPanelUiBinderImpl.java'
[ERROR] Line 17: The interface UiBinder cannot be implemented more

[ERROR] Line 17: The interface UiBinder cannot be implemented more

UiBinder<CollectionManagementLayout,SomeViewImpl> and
UiBinder<CollectionManagementLayout,SomeViewImpl>
The generated code looks like this:
public class SomeViewImpl_CollectionManagementPanelUiBinderImpl
implements UiBinder<CollectionManagementLayout, SomeViewImpl>,
SomeViewImpl.CollectionManagementPanelUiBinder {
I worked around this by changing the UiBinder declaration in SomeViewImpl
to be:
interface CollectionManagementPanelUiBinder extends UiBinder<Widget,
SomeViewImpl> {}
*My question is*: Should this have failed in GWT 2.7? Or is there a bug in
GWT 2.8?
thanks,
jay
