title: Compare String using tMap
body: <p>I am using Talend to prepare dataware.
  I want to compare the string with the contents of a column using the tMap component and create a variable to store in the DB. The problem is that the <code>==</code> operator does not give the right result (Example: <code>row2.recipient == "text"?"text":""</code>       I always get <code>""</code>) and if I use <code>.equals</code> I get errors when executing.</p>
