Component calling methods on another component

Question

I have 2 components: Repository, and Document. A repository
has an array of documents in variables scope. In each component I
use the init() method to return an instance of the object. When a
repository object is inited it generates a query of the documents
that it contains, and loops through that, calling document.init()
on each one and adding the resulting document object to the array.
When I init() a repository and use CFDUMP to view its
documents array, I get an array of the correct length containing
document objects. However, when I try to loop through the array and
call a method like getTitle() on each document, I get empty
strings. When I init() a document on its own, getTitle() works
fine. Is there something basic that I'm forgetting here?
Let me know if you need to see the more code.

In the Repository's init() method:
<cfloop query="qDocuments">
<!--- create empty document object --->
<cfset document =
createObject("component","Document").init(qDocuments.id)>
<!--- add empty document to array --->
<cfset arrayAppend(variables.documents,document)>
</cfloop>
In the front end
<!--- show documents for this repository --->
<cfset arr_documents = repository.getDocuments()>
<cfloop from="1" to="#arrayLen(arr_documents)#"
index="i">
<cfset doc =
createObject("component","/docmanager_v2/components/Document")>
<cfset doc = arr_documents[ i ]>
<cfoutput>Title: #doc.getTitle()#, Summary:
#doc.getSummary()#, Keywords:
#doc.getKeywords()#<br></cfoutput>
</cfloop>
Now I'm doing createObject twice but I guess that makes
sense... I wish I knew the principle at work here though...
