As it turns out, there appears to be a bug in DataServices. To be more specific, the DataStore object that sits between the DataService and the server does not dispatch a result or fault event when the second DataService connects via the DataService.connect() call. --- In flexcoders@yahoogroups.com, Geoffrey [EMAIL PROTECTED] wrote: Adobe support thought that it might be that too, but it doesn't look like that's the issue since it didn't really do anything different when I commented that out. --- In flexcoders@yahoogroups.com, Geoffrey gtb104@ wrote: I'll try using the TraceTarget class.

RE: [flexcoders] Re: LCDS: Debug RTMP Traffic
Yeah, it looks like somehow you are getting a DataService trying to use a DirectHTTPChannel.That only works for for HTTPService, and WebService. DataService needs a channelSet which supports AMF (AMFChannel, or RTMPChannel). I'm confused how you are getting into this situation though... those get created on the client via the endpoint property on some services or you can define one explicitly in ActionScript or MXML.Can you show how this tasks destination is getting defined in ActionScript? How is its channelSet specified - on the client via the channelSet property or on the server? If it is on the server, make sure you are compiling against the services-config.mxml file (it is a project/compiler option).

Our endpoints are created in the services-config.xml, and the destinations for DataServices are configured in data-management-config.xml. the RTMP endpoint config is as such: channel-definition id=my-rtmp class=mx.messaging.channels.RTMPChannel endpoint url=rtmp://localhost:2039 class=flex.messaging.endpoints.RTMPEndpoint/ properties idle-timeout-minutes30/idle-timeout-minutes /properties /channel-definition A DataService destination looks like: default-channels channel ref=my-rtmp/ /default-channels destination id=tasks adapter ref=java-adapter / properties use-transactionstrue/use-transactions sourceblah.blah.blah.TasksDelegate/source scopeapplication/scope cache-itemsfalse/cache-items metadata identity property=id/ /metadata network subscription-timeout-minutes0/subscription-timeout-minutes paging enabled=false/ /network /properties /destination The two destinations are identical, except for the source class.

RE: [flexcoders] Re: LCDS: Debug RTMP Traffic
Can you check if it works if you comment out the cacheId setting?Since the offline feature also persists configuration, it might be that it has cached something invalid. If it works, you might try removing your shared objects (for flash) and sql-lite database files (for air) If you could also send me the entire flashlog.txt - (probably offlist - [EMAIL PROTECTED] since it is can be big) I'll see if I can track down what is going on. I thing that is helpful to debug config problems is to look at the value of the variable mx.messaging.config.ServletConfig.xml - it is the information which is compiled into the SWF. In this case, I'd expect to see the default channels for the RTMP channel and then the destination info. The destination info looked correct from the snippet you sent previously so it is the default channels part that is messed up.
