title: upgrading from primefaces 4.0 to 5.0 problems
body: <p>I have a dynamic web project in eclipse running on Glassfish. </p>
  
  <p>It was running fine on Primefaces 4.0 but I wanted to upgrade to 5.0 to use some of the new features. I deleted the "primefaces-4.0-jar" file and copied "primefaces-5.0.jar" into WEB-INF -> lib. </p>
  
  <p>But when i run the project i get the error:<br>
  <code>org.primefaces.config.ConfigContainer.isTransformMetadataEnabled()Z</code></p>
  
  <p>I tired cleaning the project and restarting the server. I noticed on the console it still says the project is running version 4.0. 
  Is there a file or some project setting i need to change in order for the project to run with 5.0?</p>
  
  <p>Thanks</p>
