Background parallel HTTP request (ASP.NET callback logic)

[David Wilson]

I was wondering if JSF has something like the ASP.NET 2.0 callback logic? The callback can be used to do backend validation as the user is entering in information without having to refresh the page.   This is a link to the article that describes this. http://msdn.microsoft.com/msdnmag/issues/04/08/CuttingEdge/   If JSF does not do this, could it? I am unaware of a way to have _javascript_ perform a parallel/hidden call to an HTTL or Web services server.   Thank you, David ******************************************************** David Wilson [EMAIL PROTECTED] Staff Software Engineer Relevant Business Systems 678-477-0007 ext. 8702 (Fax) 678-477-0010   Please send complaints to /dev/null ********************************************************
