Firstly, apologies for the dumb question, I'm just starting out with JSF (installed mojarra 2.1.1-FCS).
Would anyone kindly suggest how I go about:
1) Making a link that doesn't refresh the page (commandLink & ajax?)
2) After clicking the link, if a response string is received, then hide the link and print the string.
I'm thinking of a login link that, (e.g. if a cookie already exists) transforms into a welcome message.
I'd very much appreciate your assistance, as I'm finding it very difficult to understand how to do this with JSF so far.
