title: quickfixj Market Data can't get group field
body: <p>"8=FIX.4.29=11435=W49=TEST56=MYTEST234=552=20180614-21:36:4955=HKGUSD268=2269=0270=1.0271=20269=1270=0.0271=0262=010=179"
  My scala processes this with "58=Conditionally Required Field Missing372=X"</p>
  
  <p>Here is the code snapit:</p>
  
  <pre><code>msg: MarketDataIncrementalRefresh
  val group = new MarketDataIncrementalRefresh.NoMDEntries()
  msg.getGroup(1, group) // this is already throwing out that error
  </code></pre>
  
  <p>I pasted the fix message to the online parser and seems ok to get all the field back.
  My cfg file has UseDataDictionary=N would this matter?</p>
