I custom my resourceBundle so it looks for messages from Database with caching on message table instead of the message properties file. The webapp work smoothly fine on it, but when I am using some very slow internet desktop, the webapp throwing me this exception. Any Help??

Code:
javax.faces.FacesException: javax.el.PropertyNotFoundException: /WEB-INF/flows/login/login.xhtml @25,100 value="#{resourceBundle['label.email']}": Property 'label.email' not found on type org.springframework.web.context.support.GenericWebApplicationContext
