Multiple operation using the same port does not work

Question

I am trying to have multiple operations on both ports
here is my wsdl snapshot
     <portType name="CommonAlerter">
          <operation name="initiate">
               <input message="client:CommonAlerterRequestInitMessage"/>
          </operation>
          <operation name="StartWait">
               <input message="client:CommonAlerterRequestInitMessage2"/>
          </operation>
          <operation name="StopWait">
               <input message="client:CommonAlerterRequestInitMessage3"/>
          </operation>
     </portType>
     <portType name="CommonAlerterCallback">
          <operation name="onResult">
               <input message="client:CommonAlerterResponseMessage"/>
          </operation>
     </portType>
I just added two new methods "StartWait" and "StopWait" to the default async. template that got generated when I created a new BPEL Project "CommonAlerter"
Now I call this BPEL process from another BPEL project
The three methods I call "initiate", "StartWait" and finally "StopWait" are at different stages in my calling BPEL processes. Although "initiate" gets called first.
When I debug the calling process instance I get an error on the call to "StopWait" which gets called after "StartWait".
Here is the error message
Exception not handled by the Collaxa Cube system.
An unhandled exception has been thrown in the Collaxa Cube system. The exception reported is: "ORABPEL-08010
Failed get operation definition.
Failed to get the WSDL operation definition of "StopWait" in portType "{http://xmlns.oracle.com/CommonAlerter}CommonAlerter".
Please verify that operation "StopWait" is defined in portType "{http://xmlns.oracle.com/CommonAlerter}CommonAlerter".
Now I do have this method in my WSDL
Can some one help.
My Message part XSD is
     <element name="CommonAlerterProcessInitRequest">
          <complexType>
               <sequence>
                    <element name="initializeparam" type="string"/>
               </sequence>
          </complexType>
     </element>
     <element name="CommonAlerterProcessResponse">
          <complexType>
               <sequence>
                    <element name="result" type="string"/>
               </sequence>
          </complexType>
     </element>
     <element name="CommonAlerterProcessRequest2">
          <complexType>
               <sequence>
                    <element name="waittime" type="duration"/>
               </sequence>
          </complexType>
     </element>
     <element name="CommonAlerterProcessRequest3">
          <complexType>
               <sequence>
                    <element name="stopargument1" type="string"/>
<element name="stopargument2" type="string"/>
               </sequence>
          </complexType>
     </element>

Here are the steps for multi operation synchronous BPEL process :
1.     Create a new BPEL process and delete request and response activities.
2.     Now add the porttype/operation in the BPEL process wsdl.
3.     Start the Process with a Pick activity and click on Create Instance checkbox. Remove the onAlarm branch as we do not need this. In the onMessage branch specify the name of the operation.
4. Now add onMessage branches to match the number of operations. The flow for each onMessage branch is different. Just make sure that you create a reply activity at the end with the correct operation chosen. So you might end up having multiple return activities.
Sometimes, a wsdl with multiple operations might not work as expected if the process version is 1.0. So try changing the process version in case you are not getting the expected results.
