The following error message is shown when an action method of a <h:commandLink/> JSF tag is called:

PWC3999: Cannot create a session after the response has been committed

The meaning of the error message is very straightforward, but my question is how the response could have been committed before the action method finishes execution.

(This error is only occurring time to time, not every time the commandLink is clicked.)

The workaround in this post solved the issue for me:
viewtopic.php?f=3&t=13151#p43963

It involves using a 'pre-render view' event and forcing the session to be created early in the rendering phase.

Jim,

I wonder if the preRenderViewEvent and applicationScopeBean would solve the p:schedule issue that myself and this other person has been experiencing. Please see posts below. I've provided my code in the last link below.
