Here is the @UiHandler method in question:
@UiHandler("table")
protected void onTableEvent(TableEvent<Publisher> event) {
int row = event.getRow();
int col = event.getColumn();
Publisher p = this.data.get(row);
switch (col) {
case 4:
this.presenter.onEdit(p);
break;
default:
this.presenter.onShow(p);
}
}
When instantiating the class containing this method, I get the
aforementioned error.
