Dispatch error, missing response.

Hi,

(soapUI Pro 4.6.3)

I have created a project, uploaded a wsdl and created a mockservice.

The mockservice has 6 operations. One of them is 'Pong'.

From an application I send such a Pong request to this mock:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:eb="http://www.oasis-open.org/committees/ebxml-msg/schema/msg-header-2_0.xsd" xmlns:xlink="http://www.w3.org/1999/xlink">
<soap:Header>
<eb:MessageHeader eb:version="2.0" soap:mustUnderstand="1">
<eb:From>
<eb:PartyId eb:type="urn:osb:oin">00000001819697461000</eb:PartyId>
</eb:From>
<eb:To>
<eb:PartyId eb:type="urn:osb:oin">00000004000000002000</eb:PartyId>
</eb:To>
<eb:CPAId>CPAID_ST_CORV_VTO</eb:CPAId>
<eb:ConversationId>e4447623-9a78-4019-9c04-31a49438034</eb:ConversationId>
<eb:Service>urn:oasis:names:tc:ebxml-msg:service</eb:Service>
<eb:Action>Pong</eb:Action>
<eb:MessageData>
<eb:MessageId>92b0c77d-1568-451a-a74d-1918197c0ea9@derks00.locgov.nl</eb:MessageId>
<eb:Timestamp>2015-06-30T07:30:38Z</eb:Timestamp>
<eb:RefToMessageId>zrg_49438034-4019-9c04-31a-12345@corv</eb:RefToMessageId>
</eb:MessageData>
</eb:MessageHeader>
</soap:Header>
<soap:Body/>
</soap:Envelope>

In the mock I get an error: [dispatch error; missing response].

I think is has to do with the body being empty (what is in fact how it should be) because in some other operations I send a message with a body not empty (again in that case what it shoud be) and they seem to work fine.

Any help would be appreciated.

Can provide you with wsdl if neccesary.

Thanks

Jack
