Re: access to error messages attributes with unitfied EL

[Bernhard Huemer <be...@gmail.com>]

Hello,

actually there are two different implicit objects dealing with the 
current request: "request" and "requestScope".

"request" -> externalContext.getRequest();
"requestScope" -> externalContext.getRequestMap();

Accordingly, it should work using the following expression: 
#{requestScope['javax..servlet.error.message']}

regards,
Bernhard Huemer
