		1	First of, it's handy to add a convenience method to your "page" component to define this "list" of objects:
		2
		3	{{panel}}
		4
		5	protected void addObjectToPathComponents(Object anObject, String aPageName, Object aTitle)
		6	{
		7	if ( anObject !=_null_)
		8	____{
		9	______Map__aMap_=_new_HashMap();
		10	______
		11	______aMap.put(_Path.ObjectKey,_anObject_);
		12	______aMap.put(_Path.PageNameKey,_aPageName_);
		13	______aMap.put(_Path.TitleKey,_aTitle_);
		14	______
		15	______this.pathComponents().add(_aMap_);
		16	______
		17	______return;
		18	____}
		19	____
		20	____throw_new_IllegalArgumentException_(_"Page.addObjectWithPageNameAndTitleToPath:_null_object.");
		21	__}
		22
		23	{{/panel}}
		24
		25	Now,//in//each//concrete//page//you//could//initialize//the//path//components:
		26
		27	{{panel}}
		28
		29	__protected_void_initPathComponents()
		30	__{
		31	____Envelope__anEnvelope_=_this.value();
		32	____Date____aDate_=_anEnvelope.creationDate();
		33	____List____aList_=_anEnvelope.list();
		34	____
		35	____this.addObjectToPathComponents(_aDate,_"Timeline",_"TIMELINE"_);
		36	____this.addObjectToPathComponents(_aDate_);
		37	____
		38	____if_(_aList_!= null )
		39	{
		40	this.addObjectToPathComponents( aList );
		41	}
		42
		43	this.addObjectToPathComponents( anEnvelope );
		44	}
		45
		46	{{/panel}}
		47
		48	Finally, the path component itself could look like this:
		49
		50	{{code}}
		51
		52	{panel}
		53	<webobject name = "IsMain">
		54	<webobject name = "MainLink"><webobject name = "MainLabel"></webobject></webobject>
		55	</webobject>
		56
		57	<webobject name = "IsNotMain">
		58	<webobject name = "Components">
		59	<webobject name = "HasPrefix"> <webobject name = "Prefix"></webobject> </webobject><webobject name = "Component"></webobject>
		60	</webobject>
		61
		62	<webobject name = "HasPrefix"> <webobject name = "Prefix"></webobject> </webobject><webobject name = "LastComponent"></webobject>
		63	</webobject>
		64	{panel}
		65
		66	{{/code}}
		67
		68	{{panel}}
		69
		70	Components: WORepetition
		71	{
		72	count = count;
		73	index = index;
		74	};
		75	IsMain: WOConditional{
		76	condition = isMain;
		77	};
		78	IsNotMain: WOConditional{
		79	condition = isMain;
		80	negate = true;
		81	};
		82	ainLink: WOHyperlink{
		83	action = getMail;
		84	title = "get new mail";
		85	};
		86	MainLabel: SpanString{
		87	value = "get mail";
		88	isSmall = true;
		89	isUpperCase = true;
		90	//isBold = true;
		91	class = "Label";
		92	length = 30;
		93	};
		94
		95	HasPrefix: WOConditional{
		96	condition = hasPrefix;
		97	};
		98	Prefix: WOImage{
		99	src = prefixUrl;
		100	border = 0;
		101	align = "middle";
		102	};
		103	Component: Link{
		104	value = component.object;
		105	description = component.title;
		106	altDescription = component.title;
		107	value = component.object;
		108	pageName = component.pageName;
		109	isUpperCase = true;
		110	isSmall = true;
		111	//isBold = true;
		112	class = "Label";
		113	};
		114	LastComponent: SpanString{
		115	value = lastComponentTitle;
		116	isSmall = true;
		117	isUpperCase = true;
		118	//isBold = true;
		119	class = "Label";
		120	length = 30;
		121	};
		122
		123	{{/panel}}
		124
		125	That's all folks.
