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
