title: How do I implement IF in mulesoft
body: <p>I want to make a decision in a Mulesoft flow, and have looked at the Choice Flow Control.  My problem, is that I want to do something if the condition is true, and nothing if it is false, something like:</p>
  
  <pre><code>if (condition == true)
     do some work
  </code></pre>
  
  <p>or, in probably incorrect xml:</p>
  
  <pre><code>&lt;choice doc:name="call a subflow if the test is true"&gt;
      &lt;when expression="#[flowVars.someVariable == True]"&gt;
          &lt;flow-ref name="doSomething" doc:name="do another thing"/&gt;
      &lt;/when&gt;
  &lt;/choice&gt;
  </code></pre>
  
  <p>no else clause, and no default flow.  How is this implemented in a Mulesoft flow?
  I could cheat, and throw a logging call into a default flow, but I would prefer not to.</p>
