IWS - Generated WSDL

Hi,

I noticed that within the generated WSDL after setting up a IWS service,
the soapAction is no longer specified within the binding element. Any ideas?

Is this something that I need to configure when setting up the IWS server?

<binding name="CUSTOMERServicesPortBinding" type="tns:CUSTOMERServices">
<soap:binding style="document" transport="
http://schemas.xmlsoap.org/soap/http"/>
<operation name="searchcustomer">
<soap:operation soapAction=""/>
<input>
<soap:body use="literal"/>
</input>
<output>
<soap:body use="literal"/>
</output>
</operation>

I would expect that the soapAction would be searchcustomer which is the
same as the operation name?

Many thanks,
Eric
