Problem calling ALSB web service using service control

Hello,

We've created a proxy service using AquaLogic Service Bus. Using ALSB's test
console we've verified that the proxy service works fine when provided XML that
conforms to the WSDL's schema.

We then created a page flow portlet in workshop that is supposed to call the
proxy service using a service control based on the WSDL just mentioned. So we
have a form with all the parameters needed to complete the request. When we
actually submit the form, ALSB complains that the SOAP request received does not
conform to the WSDL. We looked in ALSBs log, and we found that the request
coming in looked quite different from the one that is generated when using ALSBs
test console.

Could someone tell me why this is happening and how to solve it? Has anyone
successfully called an ALSB proxy service from a portlet?
