    Unspecified error on s:button

    Y E Newbie

      Hello,


      I came across some rather strange behaviour of tag s:button.
      I have an onbeforeunload event on my page that asks the user whether to continue or not with certain actions. The problem I have is this: if the user clicks on a s:button element and selects to stay on the current page an “Unspecified error” appears, although it does not seem to be having any effect on the result. The same action with s:link works fine.

      Below is a test page that demonstrates this.

                        </div>        
                      </body> 
              </html> 
      </f:view> 






      I'm using seam 2.1.1.GA and the application runs in IE6.


      Does anybody have an idea what might be causing this? Or is it a bug?


      Thanks.
