While trying to create a FormPanel that uploads a file, my application
launches a pop-up window on FormPanel.submit(). Furthermore, the
listener designed to retrieve the results from the submit never gets
fired. I'm using the latest GWT 1.7. Below is a simplified example
that reproduces the issue:
public void onModuleLoad() {
// Setup form
final FormPanel form = new FormPanel();
form.setEncoding(FormPanel.Encoding.MULTIPART);
form.setMethod(FormPanel.Method.POST);
form.setAction("uploadServlet");
// Add submit response handler: Never gets called!
form.addListener(Events.Submit, new Listener<FormEvent>() {
public void handleEvent(FormEvent event) {
Info.display("Form was
submitted",event.getResultHtml());
}
});
// Add button for submit
form.add(new Button("Submit", new SelectionListener<ButtonEvent>()
{
@Override
public void componentSelected(ButtonEvent ce) {
form.submit();
}
}));
RootPanel.get().add(form);
}
