Hi there, On our development team we're using the latest version of Mozilla 1.0.3 and Tapestry 3.0.2. We sometimes see bizarre behavior with the back button where we click back and part of the server's classpath is displayed at the bottom of the screen. Sometimes it's not the classpath but part of the rendered html from the page. The problem is not easily re-creatable, it just happens from time to time. When viewing the html source, this extraneous stuff appears AFTER the <!-- Render time: ~ 634 ms --> block of the page that was rendered. And for the case of part of the classpath being in the html source, there was an <li> tag between each part of the classpath. Has anyone ever seen this before? I don't believe the back button is even causing a repost to the server, so why would this extra information be coming out on the screen? We suspected perhaps that an exception was occurring and the classpath or parts of the html were coming from Tapestry's error page. (we have a Base64 class for encoding objects in hidden fields that can throw and subsequently eat nullpointer exceptions when it's done encoding and trying to close it's output stream) Could that in some way be part of the problem? (again it doesn't appear to be reposting when the back button is clicked so I'm not sure that this could be it). - Reid
