Extending the "109.CorrelationSets" scenario

Question

Hi!!
I'm trying to make a simple conversation.
I'm extending the "109.CorrelationSets" scenario, with one more pair of interactions (extra messages below).
I have:
op1:Customer -> Buyer : POMessage (same op)
op2:Buyer -> Seller : POMessage (same op)
op3:Seller -> Buyer : POResponse (same op)
op4:Buyer -> Seller : POResponse (new extra message)
op5:Seller -> Buyer : POResponse (new extra message)
op6:Buyer -> Cusyomer: POResponse (same op)
I'm having errors in this new scenario.
As I need to add a new operation for op4 (because the message type is not the same).
1) --------------------------------------
I put this new operation on the same portType.
<portType name="Seller">
<operation name="AsyncPurchase">
<input message="smsg:POMessage"/>
</operation>
<operation name="AsyncPurchase2">
<input message="smsg:POResponse"/>
</operation>
</portType>
But I received the following error (server error):
<<Failed get operation definition. Failed to get the WSDL operation definition of "AsyncPurchase2" in portType "{http://samples.otn.com/seller}Seller".>>
I verify and it has on the WSDL file deployed.
2) --------------------------------------
I put the new operation on a separated PortType.
<portType name="Seller">
<operation name="AsyncPurchase">
<input message="smsg:POMessage"/>
</operation>
</portType>
<portType name="Seller2">
<operation name="AsyncPurchase2">
<input message="smsg:POResponse"/>
</operation>
</portType>
<portType name="Buyer">
<operation name="AsyncPurchaseResponse">
<input message="smsg:POResponse"/>
</operation>
</portType>
<plnk:partnerLinkType name="Seller">
<plnk:role name="SellerProvider">
<plnk:portType name="tns:Seller"/>
</plnk:role>
<plnk:role name="BuyerRequester">
<plnk:portType name="tns:Buyer"/>
</plnk:role>
</plnk:partnerLinkType>
<plnk:partnerLinkType name="Seller2">
<plnk:role name="SellerProvider">
<plnk:portType name="tns:Seller2"/>
</plnk:role>
</plnk:partnerLinkType>
And I received the error (bpelc):
<<WSDL generator cannot handle the number portTypes.
WSDLGenerator cannot support "3".>>
Any ideas on what can I do?
Thanks

Hi Glenn..
You are right about the WSDL problem. Thanks…
But now I have another problem.
The instances, of the buyer, receive a NullPointerException, after doing operation Invoke2
(the Seller receive that message, and replies).
I can't solve that.
The log file has this error:
<<Failed to handle dispatch message ... exception Message handle error.
An exception occurred while attempting to process the message "com.collaxa.cube.engine.dispatch.message.delivery.ResolveCallbackMessage"; the exception is: RuntimeException; CausedByException is: null >>
Here is the content of Buyer.bpel file:
<process name="Buyer" targetNamespace="http://samples.otn.com/buyer" suppressJoinFailure="yes" xmlns:buyer="http://samples.otn.com/buyer" xmlns:seller="http://samples.otn.com/seller" xmlns:cor="http://samples.otn.com/supplyCorrelation" xmlns:smsg="http://samples.otn.com/supplyMessages" xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/">

</correlations>
</invoke>
<receive partnerLink="Seller" portType="seller:Buyer" operation="AsyncPurchaseResponse" variable="output3" createInstance="no" name="receive2">

<correlation set="Invoice" initiate="no"/>
</correlations>
</receive>
<invoke partnerLink="Customer" portType="buyer:Customer" operation="onResult" inputVariable="output3">
</invoke>
</sequence>
</process>
Any ideias?
I send the files by email (just in case).
Thanks...
