[Lift] Odd XML parsing issue

Ewan Thu, 30 Jul 2009 10:57:52 -0700

Not sure what I have messed up here but if I have a hardcoded link in
a template page where the href includes query params the lift runtime
stacktraces.  As an example <a href="http://www.yahoo.com?
a=4&b=5">Test</a> blows up - see below.  Removing the &b=5 and all is
well.  The doctype is:


?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml";
        xmlns:lift="http://liftweb.net/";>

Running Liftversion1.1-SNAPSHOT built on Thu Jul 30 18:14:47 BST 2009.

The stacktrace...
