topic subscription fiiter error

Hi All,

      I'm using servicebus 1.1 for windows server.

      I want to transfer one message from one topic to another topic, and subscription first only have default rule    

     and default rule filter is " ProcessType= 'PUBLISH' ",  message can't transfer to destination topic successfully and

     DeadLetterReason is 'The transfer  destination entity does not exist.' (actually destination topic exists)     

     but when I add another rule,which filter is '1=1', to same subscription,this message can transfer to destination 

     topic successfully.

     when I try to repeat this problem  at another servicebus namespace (two namespaces have same entity

     structure),message can transfer to destination topic successfully (with only one default rule in subscription)

     I'm very puzzled aboud what's the root cause of deadletter reason ''The transfer  destination entity does not exist.' '

     and why two namespaces  have different result according to same problem?

     Could someone help me? thank you very much
