title: Problem with Jasig CAS webflow
body: <p>I have CAS 3.4.3 in my pom. From Jasig CAS zip I included all configuration including login-webflow.xml</p>
  
  <p>The same configuration was working for me when I built my application with CAS source. Currently I get an exception:</p>
  
  <pre><code>org.springframework.expression.spel.SpelParseException: EL1041E:(pos 33): After parsing a valid expression, there is still more data in the expression: 'neq'
      at org.springframework.expression.spel.standard.InternalSpelExpressionParser.doParseExpression(InternalSpelExpressionParser.java:118)
  </code></pre>
  
  <p>Has anyone encountered this kind of error? It happens when InternalSpelExpressionParser is evaluating flowScope.ticketGrantingTicketId neq null</p>
  
  <p>is this sample login-webflow.xml even correct? I have looked through several references and haven't found anything on expression 'neq'...</p>
  
  <p>My login-webflow.xml is exactly the same as found <a href="https://developer.jasig.org/source/browse/jasigsvn/cas3/tags/cas-server-3.4.3/cas-server-webapp/src/main/webapp/WEB-INF/login-webflow.xml?r=HEAD" rel="nofollow">here</a></p>
