I'm having the following problem with BizTalk Server 2004:

I have a Send Port Group with two Send Ports.  Each Send Port has a filter
on a promoted property, and they are mutually exclusive.  I expected that if
the Send Port Group picks up a message, only one of the Send Ports will send
it.

However, when I send via the Send Post Group BOTH Send Ports send the
message, even though the filters are mutually exclusive.

I tested that the filters were correct by removing the Send Port Group and
adding a Receive Port that publishes the message.  Only one of the Send
Ports sends the message, so the filters work as expected.

Why am I getting this behaviour?  Is it by design?

Regards

Andrew

P.S.
The reason for having  the Send Post Group was so that I can bind to port
when sending from and orchestration.

When you put a filter on your send port, and then enlist it, you get a
subscription for that send port, so each port will have a subscription of
its own.  When your send port group has a filter it has the subscription and
then sends the message to each send port.  The filters for those send ports
do not come into play at that time.

It sounds like what you want is a dynamic port or a role link.  A send port
group is really for sending to a group of send ports, all of them.  If you
have two ports and you need to decide which to use, then you want a dynamic
port.  You might also want to use role links in your orchestration to
accomplish this if the ports differ by who or what is filling the role.
