Button & ClickListener

Hi,

I’m experiencing a problem while implementing a simple button with Vaadin 7.0.0.alpha1

Here’s code snippet

    
final Button button = new Button("hello", new Button.ClickListener() {
      public void buttonClick(Button.ClickEvent event) {
        // do any stuff here
      }
    });

The result of pushing the button in the browser is


in Chrome

Communication problem
Take note of any unsaved data, and click here to continue.
(SyntaxError): Unexpected identifier - Original JSON-text: html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

Some JS problem I guess?

This looks a lot like
http://dev.vaadin.com/ticket/8274
. You can test using the nightly build from 21.01.2012 instead of the alpha1 release. It should not contain any major changes compared to the alpha1 release, but some defects have been fixed.

Me also getting this issue:
“NetworkError: 504 Gateway Timeout - http://220.247.223.53:8080/zmssp/UIDL?windowName=1

How to solve this?
