Alternatively, this seems like a good use of XML (which will hold the order of nodes), rather than having to call methods of a CFC just to put in navigation items. You could then feed the XML to your CFC when you initialize it, have it parse the XML appropriately, then have the retrieval methods of your CFC return what's most useful to your UI.

Hi everyone,
I'm trying to use a structure to hold the navigation scheme for a site. Unfortunately, the fact that "structure keys are unordered" as the livedocs tell me, is causing a problem. Here's what I'm doing.
I use the addItem method of my CFC to add new items to my navigation.
<cfset addItem("Overview", "title.cfm")> <cfset addItem("Table of Contents", "toc.cfm")> <cfset addItem("Tasks", "tasks.cfm")> <cfset addItem("Details", "details.cfm")> <cfset addItem("Project Team", "team.cfm")>
addItem looks like so:
<cffunction name="addItem" displayName="Add Item" hint="I add a navigation item to a navigation block." access="public" returnType="boolean" output="false"> <cfargument name="LinkName" type="string" required="true"> <cfargument name="PageName" hint="The .cfm page to link to" type="string" required="true"> <cfset var local = StructNew()> <cfset local.item = StructNew()> <cfset StructInsert(local.item, arguments.LinkName, arguments.PageName)>
<cfset setNavigation(local.item)>
<cfreturn true> </cffunction>
setNavigation looks like this:
<cffunction name="setNavigation" access="private" returntype="VOID" output="false"> <cfargument name="NavItem" type="struct" required="true" hint="A structure containing the navigation item to add to the list"> <cfset StructAppend(variables.instance.navigation, arguments.NavItem)> </cffunction>
Variables.instance.navigation holds my navigation structure. Now, considering the order in which I added my navigation items, I would expect them to be spit out in the same order. Instead they come out like so:
Details, Table of Contents, Overview, Project Team, Tasks
Now, if structs really were unordered, I would expect that they would occassionally come out in a *different* order, but nope... They always come out in the same order, WRONG! :).
Anyone have any ideas to help me crack this nut?
Thanks,
Dan
