Missing messageId: FlexBuilder vs mxmlc


Level 1

I am using FlexBuilder 3.0.2 with Cairngorm 2.2.1 to
implement RemoteObjects over AMF.

When I run/debug/profile the project from FlexBuilder, I
receive the following error on response from a save command:

SaveObjectCommand?: Fault: event = [RPC Fault
faultString="Didn't receive an acknowledgement of message"
faultCode="Server.Acknowledge.Failed" faultDetail="Was expecting
message '5AA6C3E6-BC82-AFF3-E275-AB767CDA24C1' but received
'null'."] [AMF] FaultEvent?: faultCode:Server.Acknowledge.Failed
faultString:'Didn't receive an acknowledgement of message'
faultDetail:'Was expecting message
'5AA6C3E6-BC82-AFF3-E275-AB767CDA24C1' but received 'null'.'

When I compile the same project with mxmlc, I do not receive
the fault, and the response is processed correctly by the response

My mxmlc compile flags are:

mxmlc -context-root=http://localhost:3000/
-headless-server=true -services=src/services-config.xml -output
bin-debug/Test.swf -compiler.library-path+=libs src/Test.mxml

I have debugged the problem from the server side and
confirmed that I receive a different AMF message when the flex
client swf is compiled by mxmlc vs FlexBuilder. Does anyone know
what compile flags FlexBuilder is using that might cause a problem?

In your flex builder, go to menu "project > clean..."

Your project need to be recompiled after you update the LCDS
config files. Cleaning the project forces a recompile.

Thanks, I've tried cleaning and rebuilding all projects, but
it did not fix the problem.
