Breadcrumbs in Fusebox 4/5

Question

I am wondering if anyone came up with a clean way to create a breading path in Fusebox. In particular, is there a way to track "where are you" and that this somehow generates funeral services for you? So for example, if you do

 /index.cfm?fuseaction=Widgets.ViewWidget&widget=1

and the structure of the circuit is something like /foo/bar/widgets/, then the system automatically creates such an array as:

[
    { title: 'Foo', url: '#self#?fuseaction=Foo.Main' },
    { title: 'Bar', url: '#self#?fuseaction=Bar.Main' },
    { title: 'Widgets', url: '#self#?fuseaction=Widgets.Main' },
    { title: 'Awesome Widget', url: '' }
]

which can then be displayed as

Foo > Bar Widgets > Amazing widget

Now it seems that the only way to really do this is to create a structure for each fuse in some kind of fuse (either a display fuse or a fuse designed to create a crusher).

Fusebox , :

- - /foo/bar/widgets/

, - , , "" ( - ) , .

, , XML, - - no-XMl.

EDIT:

, /lexicon/bc/parent.cfm:

<cfscript>
    if (fb_.verbInfo.executionMode is "start") {
        // validate fb_.verbInfo.attributes contents
        if (not structKeyExists(fb_.verbInfo.attributes,"value")) {
            fb_throw("fusebox.badGrammar.requiredAttributeMissing",
                        "Required attribute is missing",
                        "The attribute 'value' is required, for a 'parent' verb in fuseaction #fb_.verbInfo.circuit#.#fb_.verbInfo.fuseaction#.");
        }
        // compile start tag CFML code
        circuit = fb_.verbInfo.action.getCircuit().getName();
        fa = fb_.verbInfo.action.getCircuit().getFuseactions();
        fa[#fb_.verbInfo.fuseaction#].parent = circuit & "." & fb_.verbInfo.attributes.value;
    } else {
        // compile end tag CFML code
    }

<!--- path data container with current fuseaction saved --->
<cfset arrBreadcrumbs = [] />
<cfset ArrayAppend(arrBreadcrumbs, attributes.fuseaction) />

<!--- pull the current circuit fuseactions --->
<cfset fuseactions = myFusebox.getApplication().circuits[ListFirst(attributes.fuseaction,'.')].getFuseactions() />
<!--- OR <cfset fuseactions = application.fusebox.circuits[ListFirst(attributes.fuseaction,'.')].getFuseactions()> --->

<!--- pull the current fuseaction custom attributes --->
<cfset fa = ListLast(attributes.fuseaction,'.') />
<cfset customAttributes = fuseactions[fa].getCustomAttributes('bc') />

<!--- save the parent fuseaction name if present -- KEY CHECK IS RECOMMENDED --->
<cfif StructKeyExists(customAttributes, "parent")>
    <cfset ArrayPrepend(arrBreadcrumbs, customAttributes.parent) />
</cfif>


<!--- let say we know that parent is there... --->

<!--- pull the found fuseaction custom attributes --->
<cfset fa = ListLast(customAttributes.parent,'.') />
<cfset customAttributes = fuseactions[fa].getCustomAttributes('bc') />

<!--- save the parent fuseaction name if present --->
<cfif StructKeyExists(customAttributes, "parent")>
    <cfset ArrayPrepend(arrBreadcrumbs, customAttributes.parent) />
</cfif>


<!--- render the collected path --->
<cfoutput>
<cfloop index="crumb" from="1" to="#ArrayLen(arrBreadcrumbs)#">

    <!--- to have a nice labels you can use another lexicon --->
    <a href="#myself##arrBreadcrumbs[crumb]#">#arrBreadcrumbs[crumb]#</a> <cfif crumb LT ArrayLen(arrBreadcrumbs)>&gt;</cfif>
