		1	First of, it's handy to add a convenience method to your "page" component to define this "list" of objects:
		2
		3	{{code}}
		4
		5	protected void addObjectToPathComponents(Object anObject, String aPageName, Object aTitle) {
		6
		7	if ( anObject != null ) {
		8	Map aMap = new HashMap();
		9
		10	aMap.put( Path.ObjectKey, anObject );
		11	aMap.put( Path.PageNameKey, aPageName );
		12	aMap.put( Path.TitleKey, aTitle );
		13
		14	this.pathComponents().add( aMap );
		15
		16	return;
		17	}
		18
		19	throw new IllegalArgumentException ( "Page.addObjectWithPageNameAndTitleToPath: null object.");
		20	}
		21
		22	{{/code}}
		23
		24	Now, in each concrete page you could initialize the path components:
		25
		26	{{code}}
		27
		28	protected void initPathComponents()
		29	{
		30	Envelope anEnvelope = this.value();
		31	Date aDate = anEnvelope.creationDate();
		32	List aList = anEnvelope.list();
		33
		34	this.addObjectToPathComponents( aDate, "Timeline", "TIMELINE" );
		35	this.addObjectToPathComponents( aDate );
		36
		37	if ( aList != null )
		38	{
		39	this.addObjectToPathComponents( aList );
		40	}
		41
		42	this.addObjectToPathComponents( anEnvelope );
		43	}
		44
		45	{{/code}}
		46
		47	Finally, the path component itself could look like this:
		48
		49	{{code}}
		50
		51	<webobject name = "IsMain">
		52	<webobject name = "MainLink"><webobject name = "MainLabel"></webobject></webobject>
		53	</webobject>
		54
		55	<webobject name = "IsNotMain">
		56	<webobject name = "Components">
		57	<webobject name = "HasPrefix"> <webobject name = "Prefix"></webobject> </webobject><webobject name = "Component"></webobject>
		58	</webobject>
		59
		60	<webobject name = "HasPrefix"> <webobject name = "Prefix"></webobject> </webobject><webobject name = "LastComponent"></webobject>
		61	</webobject>
		62
		63	{{/code}}
		64
		65	{{code}}
		66
		67	Components: WORepetition
		68	{
		69	count = count;
		70	index = index;
		71	};
		72	IsMain: WOConditional{
		73	condition = isMain;
		74	};
		75	IsNotMain: WOConditional{
		76	condition = isMain;
		77	negate = true;
		78	};
		79	ainLink: WOHyperlink{
		80	action = getMail;
		81	title = "get new mail";
		82	};
		83	MainLabel: SpanString{
		84	value = "get mail";
		85	isSmall = true;
		86	isUpperCase = true;
		87	//isBold = true;
		88	class = "Label";
		89	length = 30;
		90	};
		91
		92	HasPrefix: WOConditional{
		93	condition = hasPrefix;
		94	};
		95	Prefix: WOImage{
		96	src = prefixUrl;
		97	border = 0;
		98	align = "middle";
		99	};
		100	Component: Link{
		101	value = component.object;
		102	description = component.title;
		103	altDescription = component.title;
		104	value = component.object;
		105	pageName = component.pageName;
		106	isUpperCase = true;
		107	isSmall = true;
		108	//isBold = true;
		109	class = "Label";
		110	};
		111	LastComponent: SpanString{
		112	value = lastComponentTitle;
		113	isSmall = true;
		114	isUpperCase = true;
		115	//isBold = true;
		116	class = "Label";
		117	length = 30;
		118	};
		119
		120
		121	{{/code}}
		122
		123	That's all folks.
