I need to call a SOAP service using HTTP connector to have an external system generate an id for a new users. This service takes a number of parameters that identify the user (giveNamen, surname, ...). If there is already a user for a set of parameters, the service will throw a SOAP fault. In its details the fault message contains the preexisting id. How can I get to this value with Validator?

The "Get POST/PUT/DELETE Results and Set Variable" action seems to populate the target variable with the warning message text "Server returned HTTP response code: 500 for URL: https://id.xxx.net:9443/XXXIdProviderV3/XXXIdProviderService/XXXIdProviderPort" instead of the actual XML returned by the service.
