body: <p>I got an error in my quickfixj Application. First, I got an error like this:</p>
  
  <pre><code>Out of order repeating group members
  </code></pre>
  
  <p>After that, I added this text into my initiator.config:</p>
  
  <pre><code>ValidateUserDefinedFields=N
  ValidateIncomingMessage=N
  </code></pre>
  
  <p>But now I got another error in my application:</p>
