I am trying to incorporate the performance improvements using: <context-param> <param-name>org.apache.myfaces.ADD_RESOURCE_CLASS</param-name> <param-value>org.apache.myfaces.component.html.util.StreamingAddResource</param-value> </context-param>
with <t:document*> when using facelets. I am getting an exception when the first page is accessed: Unknown error while serving resource: null/header.css, message : For input string: "null" The error seems to go away after accessing the front page the first time; but I am not sure if it is an error that happens per session. Does anyone have any ideas about this? Should I not use that performance tip if using facelets?
