[UserDispatchAction] retrieve attribute from servlet context

Hi there,
on a plugIn class I store a properties object in the servlet context, like this:

ServletContext context = servlet.getServletContext();
context.setAttribute(Constants.ROLES, roles);


the question is, why if I try to retrieve that object in this way from a DispatchAction, I get a null object

private Properties props = (Properties)servlet.getServletContext().getAttribute(Constants.ROLES);


while inside the method, like this, it works fine?

Properties roles = (Properties)request.getSession(false).
getServletContext().getAttribute(Constants.ROLES);


Can you tell me if this way will strongly affect the performance?

Thanks in advance
