Question

I see this information in my jboss console, when my pages don't render properly. Does anyone know what this means?

Answer 1

When deploying a new EAR or war created from a machine with time settings different from that of the server where application is deployed, flushing of the JSF components can happen.

Logs will show the following error.

The reason being, when ever a new request is made, server sees the page as modifed in future time stamp and starts compiling again. This causes the component tree to be created again, causing to lose all the state stored by the component.

To fix this add facelets.REFRESH_PERIOD to the web.xml

REFRESH_PERIOD indicates, When a page is requested, what interval in seconds should the compiler check for changes. If you don't want the compiler to check for changes once the page is compiled, then use a value of -1. Setting a low refresh period helps during development to be able to edit pages in a running application.

web.xml, should look like this,

<context-param>
<param-name>facelets.REFRESH_PERIOD</param-name>
<param-value>-1</param-value>
</context-param>

-1indicates not to check for changes, since production servers it is safe to set this value.
