[xposted from railo-talk because no one there seems to have the answers]
I've got the latest released Railo Comunity edition, with bundled Resin, using
mod_caucho to run everything through Apache 2.2 on Ubuntu linux.
I've set up what seems like a dead simple test.
t.cfc has one remote method, get(), that createObject()'s an item.cfc which
has two cfproperty tags, and sets this.propertyName outside any method to
defaults:
<cfcomponent>
<cffunction name="get" access="remote">
<cfreturn createObject('component','item')>
I can call t.cfc from a CFM page fine:
<cfset serv=createObject('component','t')>
<cfdump var="#serv.get()#">
and it all works as expected.
So, I come to use this with RemoteObject from a Flex application.
There's no documentation for where things live in the Railo world, but I
eventually stumble across a servlet called AMFGateway that maps to
the '/flashservices/gateway' path, so figure that must be the endpointURI.
Still no joy, I get some sort of 'unknown or unsupported' error from an
OpenAMF class.
More googling reveals that OpenAMF until recently didn't do AMF3 (the Flex
default), so I guess the version of OpenAMF that comes with Railo is out of
date.
So, I have to take special steps in my Flex client to use AMF0, via
renaun.com's RemoteObjectAMF0:
<rpc:RemoteObjectAMF0
endpoint="http://dev.buyme.it/flashservices/gateway";
id="oService"
source="t"
showBusyCursor="true"
makeObjectsBindable="true"
result="result( event )"
fault="fault( event )">
This still doesn't work as I get a weird WDDXConvertor error (WDDX ? *eh* ?)
when I call 'oService.get()'.

- Serializing Message, for more info turn on debug level
-----------------------
I'm getting slightly frustrated with this, but at least it's progress I
suppose.
Has anyone got this setup (Flex RemoteObject to CFC) working ? I can share the
full ready to compile Flex and CFML code I'm using on request, as I plan to
write a full article on this once it's working.
If you've got a working example of code for both ends, please let me know.
So, questions:
1) How do I 'turn on debug level' for 'Deserializing Message' ?
2) When will the OpenAMF in Railo be updated to support AMF3 ?
3) Am I even using the right settings (i.e. endpoint URI) in my Flex
application ?
