Channel.Polling.Error

Hello,

We had an application which works on Flex 2, servebox Foundry 0.9.2 and LiveCycle 2. We wanted to migrate the application to Flex 4.

So i did all modifications and now we have Flex 4, sevebox Foundry 3.0.0 and LiveCycle 3.1.

But when I launch it (on Jboss 4.2.3) after login, first polling is done and then I have a Channel.Polling.Error. and the Falut String is

"The client has no active subscriptions over endpoint 'my-polling-amf'"

Can someone help me to resolve this problem ?

Thanks in advance for any help.
