Destination 'ColdFusionGateway' requires FlexClient support which was introduced in version 2.5....

Question

Hi,
Hopefully someone might recognise this error...
Sadly it brings up only one result on google and that's a bit
vague as to how that person got out of thier hole... :(
I'm trying some very simple Flex Messaging with Flex Builder
2.0.1 and CF8 Standard (with LiveCycle 2.5.? built in)
But I get this error:
"Destination 'ColdFusionGateway' requires FlexClient support
which was introduced in version 2.5. Please recompile the client
application with an updated client framework."
I guess the '2.5' is referring to LiveCycle?
And I guess it's saying that the Flex compiler needs some
updated elements to compile with so it can work with LiveCycle ?
I think stepping into Flex for the first time just as FDS
became LiveCycle was not a good idea.
Strangely I (may have) narrowed it down to the gatewayid tag
in messaging-config.xml
eg:
<gatewayid>*</gatewayid>
OR <gatewayid>Flex2CF2</gatewayid>
Which has been there well before LiveCycle. BUT If I remove
this tag completely the error doesn't occur... then of course
messaging doesn't work without it. Ho hum
I can't see any DataServicesMessaging In/Outs using
cf-polling-amf... I'm having more luck with cf-rtmp - I can see the
'In' and 'Out' counters ticking away when i view my ColdFusion
Event Gateway Instance in the CF admin.
So polling-amf won't connect, whereas rtmp will. Neither
channel will 'subscribe' though.
I've got ColdFusion Extensions 0.5.155475 installed (don't
ask me how - it was a nightmare!) and working in Flex Builder 2.
I tried bringing the flex/libs over to flex builder from CF
as they were newer - no good
I updated Flex Builder with:
Flex 2.0.1 SDK with HotFix 3 from
http://labs.adobe.com/technologies/flex/sdk/flex2sdk.html
But nothing helps.
here's the mxml:

Thanx Mete, yeah i did...
but i solved it some other way... not entirely sure this was
it though as i was doing a lot of things at once...
it was fds.swc... possibly it was out of date or missing.
