Page rendering error after system navigation

Asked

I have a problem with a developed system which is that as the user browses the system after a certain time the pages do not render but return when the user updates the page. I researched a lot but I could not find a solution and the error that gives does not help much to solve too.

Obs: error does not only give on the page in question "agents".

Obs. 2: the nullpointer error seems to be in a Filter class created, but still do not know what comes null to her

People after weeks researching I managed to find the solution to the problem and I report to you in case there is someone else in need as well. As I use a CDI Viewscoped ( javax.faces.view.Viewscoped ) I should then put the Bean to be managed by CDI, and this was not the case.

Workaround: Configure the following Beans manager in Web.xml (if you haven’t already done so):

<resource-env-ref>
    <resource-env-ref-name>BeanManager</resource-env-ref-name>
    <resource-env-ref-type>javax.enterprise.inject.spi.BeanManager</resource-env-ref-type>
</resource-env-ref>

Put the file context.xml the following content:

<?xml version="1.0" encoding="UTF-8"?>
 <Context>
   <Manager pathname=""/>
  <Resource name="BeanManager" auth="Container" 
     type="javax.enterprise.inject.spi.BeanManager" 
     factory="org.jboss.weld.resources.ManagerObjectFactory"/>
 </Context>

That way the pages started working perfectly.
