Do you have a corresponding field in your UIBinder ui.xml with the
same ui:field property?
For example, in your ui.xml you should have:
<g:Button ui:field="button">Click Me</g:Button>
In the corresponding Java class you should have:
@UiField
Button button;
@UiHandler("button")
void clickButton(ClickEvent e) {
Window.alert("Hello World");
}
As Steve said, the method name on the UiHandler can be anything. The
parameter to the method determines the event being handled. As long as
your ui:field property, the variable name on the UIField, and the
quoted text on the @UiHandler annotation match everything should work
fine.
