Question

I’m trying to wrap a ButtonElement into a Button:

@UiField ButtonElement myButton;

Button theButton = Button.wrap(myButton);

However, I am getting this error:

@UiField myButton, template field and owner field types don't match: com.google.gwt.dom.client.ButtonElement is not assignable to com.google.gwt.user.client.ui.Button

Answer 1

This means that while you have a ButtonElement in your java code, the uibinder tag with the name “myButton” is actually a Button widget, not a ButtonElement elt.

Change the uibinder to actually use a <button>, or change the @UiField to be a Button (and drop the wrap(...) call).
