Hey everyone,

I was updating this post from 2012 - https://community.jboss.org/en/switchyard/blog/2012/06/22/an-impatient-newbie-user-s-introduction-to-switchyard (where the reader is walked through creating a minimal SwitchYard project from scratch) when I encountered an odd problem. It looks like a request, when passed to a transformer, is corrupted.

Some background, the original post created an 'helloworld' style project that performed some string concatenation. The project requires to/from transformers to convert elements to string and then back again. (The code for the transformer was actually copied from a 2012 demo program.  ;-)

What I am seeing today, after having created a new version of the project - by the way - the editor (I'm working with 0.7) is great - I want to look at the nightly builds when I get a chance - is that a SOAP request in this format:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="tns">

   <soapenv:Header/>

   <soapenv:Body>

      <tns:sayHello>

         <!--Optional:-->

         <tns:arg0>abc</tns:arg0>

      </tns:sayHello>

   </soapenv:Body>

</soapenv:Envelope>

Results in the transformer extracting a null value for the 'arg0' parameter. The funny thing is that if the 'from' transformer performs a getTextContent() on the element that it receives, it is able to parse out the text value of the arg0 argument. I'm wondering if there is a WSDL-generation error here, as the problem seems to be in the element as it is received by the 'from' transformer - but the WSDL appears to be OK.

Does this sound familiar to anyone?

Many thanks!,

Len D.
