I've been getting the same constant problem. Currently now I'm getting the error javax.el.PropertyNotFoundException: /index.xhtml @23,97 action="#{execise04.getInput}": Target Unreachable, identifier 'execise04' resolved to null
I'm not entirely sure what I'm doing wrong here is the code. I've looked at the other post that they say solved my issue and it doesn't solve my issue, and I don't understand a single thing its saying. Its not really giving a solution just turning me around in circles. Also I have had other issues such as once i press the button before I was getting a different error and it wouldn't open the second window that is supposed to display the output. Someone please help. I've been stuck on this for days and its getting incredibly frustrating.
