Mura CMS: How to use the user's email address as the username. This would make it unnecessary to collect the username on the form itself.

usernameNotRequired.cfm

<cfscript>
  // place this in the theme's eventHandler.cfc and reload the application
  public any function onBeforeUserSave(struct $) output=false {
    var user = arguments.$.event('userBean');
    user.setUsername(user.getEmail());
    
    // you could also add custom errors like so
    var hasError = false;
    // then do some validation of input
    // .. validation would go here ..
    // if validation fails, add an error
    if ( hasError ) {
      user.getErrors().myCustomError = 'This user has a problem';
    }
</cfscript>
