java.lang.IllegalStateException: CDATA tags may not nest

Question

I\'ve got a problem with an ajax request in a JSF page. When I click on the button, I get this exception:

SEVERE: Servlet.service() for servlet Faces Servlet         


        

Answer 1

If you also see java.lang.ClassCastException: com.sun.faces.facelets.compiler.UIInstructions cannot be cast to org.primefaces.component.tree.UITreeNode in the server log, add

  javax.faces.FACELETS_SKIP_COMMENTS
  true

to /WEB-INF/web.xml
