title: WSO2 DAS Empty data in stream
body: <p>I'm starting to use WSO2 DAS to publish some data from WSO2 ESB for monitoring purpose.</p>
  
  <p>I configured the stream on both sides (ESB/DAS) but when I send the data to the DAS I just get an empty row in the DAS database. I checked both parameter names and I checked the XPath expressions in ESB and everything seems OK. Obviously I'm missing something.</p>
  
  <p>Thanks for your help.</p>
