Access to transfer from onException

[paulFusion]

I'm fairly new to transfer, and loving it so far. However I've run
into a problem which has me stumped.

I'm trying to get access to a transfer object from within my
onException handler. Here's what I think is the pertinent code:

<cfcomponent name="main" extends="coldbox.system.eventhandler"
output="false" autowire="true">

<cfproperty name="Transfer" type="ocm" scope="instance">

...

<cffunction name="onException" access="public" returntype="void"
output="false">
<cfargument name="Event" type="coldbox.system.beans.requestContext">

<cfset var page = instance.transfer.readByProperty("admin.Page",
"urlFriendly", cgi.PATH_INFO)/>
...


It looks just like all my other attempts to autowire transfer into my
event handlers, which work fine. When I attempt to do so in the
exception handler though, I get the following error:

Error Messages: Element TRANSFER is undefined in a Java object of
type class [Ljava.lang.String;.


I've also tried the _wireme="ocm" approach, with the same results.


Is there any reason why autowire wouldn't work in an exception
handler? Any other way to get access to the transferLoader object?

Thanks,
-paul

Oops... saw the posting instructions after the fact.
Also, I meant to say "fairly new to Coldbox".

Coldbox 2.6.2 (although maybe that goes without saying since I'm using
transferLoader)
ColdFusion 8.0.1
Windows 2003

Here's my trace:

Well, not sure what my issue was, but it turns out I really wanted to
use onInvalidEvent anyway. And the transfer injection seems to be
working just fine there.

For now I'm just attributing this to the intergnomes, and I'm moving
on.
