After upgrading to tapestry 4.0.2 and tacos 4.0.0, my page with autocompleter does not work anymore. I get the behaviour described in the tacos FAQ about IE problems:
http://tacos.sourceforge.net/faq.html#faq-N100A2 The page loads in IE when the autocompleter is removed, when the autocompleter is there, IE cancels page load and displays the error dialog described in the link. The solution suggested doesn't apply to me, because I don't use the shell component, and no base tag is rendered. Any ideas? I've been through similar symptoms before, with the datepicker in contrib, bug report here: http://issues.apache.org/jira/browse/TAPESTRY-788
