WARNING: JSF1091: No mime type could be found for file dynamiccontent

Try adding the following to your web.xml file

<mime-mapping>
    <extension>jsp <!--{or the extension of file}--></extension>
    <mime-type>text/html</mime-type>
  </mime-mapping>

I found one solution.

by using the latest version of primefaces (3.5).

<dependency>  
    <groupId>org.primefaces</groupId>  
    <artifactId>primefaces</artifactId>  
    <version>3.5</version>  
</dependency> 

but there will unpleasant changes in IHM
