[zspitzer]

<cfscript>
	public string function renderPage( required any page, required any docTree, required boolean edit ){
		try {
			var renderedPage = renderTemplate(
				  template = "templates/#_getPageLayoutFile( arguments.page )#.cfm"
				, args     = { page = arguments.page, docTree=arguments.docTree, edit=edit }
				, helpers  = "/builders/html/helpers"
			);
		} catch( any e ) {
			e.additional.luceeDocsPageId = arguments.page.getid();
			rethrow;
		}
	}
<cfscript>

throws MISSING_VAR: Variable e is not declared with a var statement.
