Unspecified error on s:button 
------------------------------

                 Key: JBSEAM-4544
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4544
             Project: Seam
          Issue Type: Bug
          Components: JSF Controls
    Affects Versions: 2.1.1.GA
         Environment: IE6,IE8
            Reporter: Sam Kid
            Priority: Optional

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:
