WCF serializing response from JAX WS to an empty object - possible namespace issue?

Question

I am using a WCF client to call a JAX web service.

When the response is deserialized, an array within the response object is always empty. However, if I mannually add the namespace to the array type within the response using a message inspector, the response is deserialized correctly.

So the response I get is:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" />
  <S:Body>
    <ns2:myResponse xmlns:ns2="http://mynamespace.com/">
      <myArray>
        <myObject>
          <myString>abcde</myString>
          <myInt>12345</myInt>
        </myObject>
      </myArray>
    <id>7777</id>
  </ns2:myResponse>
  </S:Body>
</S:Envelope>

and this will produce an object of type myResponse, with the correct 'id' feild but an empty array of type myObject for the myArray field.

When I manually edit the recieved message to add the namespace alias 'ns2' before the myObject tags, so that it looks like this:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" />
  <S:Body>
    <ns2:myResponse xmlns:ns2="http://mynamespace.com/">
      <myArray>
        <ns2:myObject>
          <myString>abcde</myString>
          <myInt>12345</myInt>
        </ns2:myObject>
      </myArray>
    <id>7777</id>
  </ns2:myResponse>
  </S:Body>
</S:Envelope>

the correct object is deserialized ie with a myArray of size 1 containing the correct myObject.

Can anyone tell me why this is and how I can get the WCF deserialization to work correctly without manual intervention?

Not sure if this is exactly your problem, but may be worth a try.

We had a similar problem. In our case there was a complex object that was being deserialized with several fields missing. Using a debugger we could see that the information was there. But we could not get to it through the code.

What worked for us was to cast the object to a type that included all the fields.

Check your references.cs file, which datatypes are defined there?
