I think correlation sets are ok(i have two receive activities).
I use Netbeans6.0 IDE.
Can anyone help me?
Sorry,but i don't speak English fluently

Answer 1

I can't debug it more,because the bpel variables window disappears when the proccess comes to invoke activity.
The bpel code is simple:I have got a sequence with follow activities:
receive
assign
invoke
receive
assign
reply
The code is:

</process>If it's a bug,that means that i can't use second receive after invoke any more?
