Mura CMS : How to reference information about a content item after it's been saved

muraOnAfterContentSave.cfm

<cfscript>
public any function onAfterContentSave($) {
	// reference the new bean that was created
	var newBean = arguments.$.event('contentBean');
	// reference to the OLD bean
	var oldBean = arguments.$.event('activeBean'); // can also use 'currentBean' to access the same bean
	
	// you can now reference any of the attributes of the new bean ...
	WriteDump(var=newBean.getAllValues(), abort=true);

	// keep in mind that the content has already been saved, so you can't display any messaging anymore!
	// however, you can do some additional manipulation of the content such as parse a PDF, save children, etc.
}
</cfscript>

Is the 'activeBean' null if the content has just been created?
