Andrea,

You can use Salesforce to proxy your SOAP calls.  This works from Skuid using a remote action call from a snippet.  You can also setup your apex class as an invocable action.  Then you can use the declarative action framework to make your SOAP calls.

Thanks,

If I create a custom soap client can I resolve? 

Andrea,

It is possible to connect to a SOAP service from a Skuid page.  You will need to get your Cross Origin security setup in Salesforce to allow this.

Thanks,

Bill
