Mura CMS : How to set the Content Release Date automatically, if it's not filled in

muraAutoSetReleaseDate.cfm

<cfscript>
	// Drop this function in your Site, Theme, or Plugin's eventHandler.cfc
	public any function onBeforeContentSave($) {
		// reference to the newBean
		var newBean = arguments.$.event('newBean');
		// reference to the original contentBean (in case you need it for anything)
		var oldBean = arguments.$.event('contentBean');

		// Check to see if the contentBean has a parent, and if so
		// see if it's the 'News', check the releaseDate and populate if necessary
		if ( 
			newBean.hasParent() 
			&& newBean.getParent().getTitle() == 'News' 
			&& !Len(newBean.getValue('releaseDate'))
		) {
			newBean.setValue('releaseDate', Now());
		}
	}
</cfscript>
