		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	<webobject name = "IsMain">
		51	<webobject name = "MainLink"><webobject name = "MainLabel"></webobject></webobject>
		52	</webobject>
		53
		54	<webobject name = "IsNotMain">
		55	<webobject name = "Components">
		56	<webobject name = "HasPrefix"> <webobject name = "Prefix"></webobject> </webobject><webobject name = "Component"></webobject>
		57	</webobject>
		58
		59	<webobject name = "HasPrefix"> <webobject name = "Prefix"></webobject> </webobject><webobject name = "LastComponent"></webobject>
		60	</webobject>
		61	{{/code}}
		62
		63	{{code}}
		64
		65	Components: WORepetition
		66	{
		67	count = count;
		68	index = index;
		69	};
		70	IsMain: WOConditional{
		71	condition = isMain;
		72	};
		73	IsNotMain: WOConditional{
		74	condition = isMain;
		75	negate = true;
		76	};
		77	ainLink: WOHyperlink{
		78	action = getMail;
		79	title = "get new mail";
		80	};
		81	MainLabel: SpanString{
		82	value = "get mail";
		83	isSmall = true;
		84	isUpperCase = true;
		85	//isBold = true;
		86	class = "Label";
		87	length = 30;
		88	};
		89
		90	HasPrefix: WOConditional{
		91	condition = hasPrefix;
		92	};
		93	Prefix: WOImage{
		94	src = prefixUrl;
		95	border = 0;
		96	align = "middle";
		97	};
		98	Component: Link{
		99	value = component.object;
		100	description = component.title;
		101	altDescription = component.title;
		102	value = component.object;
		103	pageName = component.pageName;
		104	isUpperCase = true;
		105	isSmall = true;
		106	//isBold = true;
		107	class = "Label";
		108	};
		109	LastComponent: SpanString{
		110	value = lastComponentTitle;
		111	isSmall = true;
		112	isUpperCase = true;
		113	//isBold = true;
		114	class = "Label";
		115	length = 30;
		116	};
		117
		118
		119	{{/code}}
		120
		121	That's all folks.
