title: Talend tExtractRegexFields match after comma syntax
body: <p>I'm trying to extract everything in a string after the first comma, using the <code>tExtractRegexFields</code> component. </p>
  
  <p>I'm splitting strings in an address field <code>(Address_1)</code> to a second address field <code>(Address_2)</code>.</p>
  
  <p>On <code>regexr.com</code>, the following syntax works perfectly: <code>,[\s\S]*$</code></p>
  
  <p>In order to comply with Talend's escape sequences, I changed that syntax to 
  <code>,[\\s\\S]*$</code>. That solved the error, but the code doesn't appear to match on anything, since nothing is split from <code>Address_1</code> to <code>Address_2</code>. </p>
  
  <p>What's wrong? Does this syntax not work in <code>Talend</code>? Are there alternate <code>Regex</code> solutions?</p>
