Intermittent Error 500: jsp.JspException: Cannot find bean: "msg" in scope: "request" 1.3

[Marcos filipe Pereira]

Hi Guys,

I have an Webb App that worked fine in DEV enviroment. So, After some tests I got this Intermittent error : Error 500: javax.servlet.jsp.JspException: Cannot find bean: "mensagemErro" in scope: "request"

That´s strange because sometimes works fine. So, Could you please help me ??
