WARNING: There should always be a submitted value for an input if it is rendered, its form is submitted, and it was not originally rendered disabled or
read-only. You cannot submit a form after disabling an input element via javascript. Consider setting read-only to true instead or resetting the disabled
value back to false prior to form submission. Component : {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /showcase.xhtml][Class:
