Can one adapter create multi event to multi channel?

Question

Hello All,
I have a socket reader adapter. I read socket data and genarate two types of events. One of them is positionEvent and other one is alarmEvent. I sent these events to seperate channels and seperate processor. But i have exception to processors. I think events sent all of the channels. Then processor throw exception.
How can I send specific event to specific channel?
Exception is :
<Jan 23, 2012 10:51:05 AM VET> <Error> <CQLProcessor> <BEA-000000> <Failed to set property [information] of event type [UnitAlarm]. Cause = [information] is not a property of event type [UnitPosition]>

Hi,
Here your SocketAdapter sends whatever data it receives to both the channels, hence depending on the event type you read you get such error which you mentioned.We can't send different type of events to different channels at adapter level, we can do this only at a processor, assigning multiple queries to respective channels.
To make this work you have to use another socket adapter for one more event type. Don't forget to mention the event-type in the adapter config, only one event-type per adapter works.
Hope this fixes your problem.
Thanks
