title: Refresh the form after lines are received
body: <p>I'm passing lines from SO to a destination form. I have created a method where I'm assigning values from SO lines in for loop in destination form dataSource which I call from initValue. Here is the code sample:</p>
  
  <pre><code>for (counter = 1; counter &lt;= conLen(c); counter++)
      {
          salesLineLocal = conPeek(c, counter);
          ttsBegin;
          .........
          table.doInsert();
          ttsCommit;
      }
  </code></pre>
  
  <p>When initialization is done and form opens I see only 1 line despite of let say 3. but when I press F5 all lines are shown correctly.
  So, what I'm doing then is to refresh table_ds by code after for loop.
  I tried table_ds.research(); but did not help. Then I tried element.task(#taskF5); but neither it hepled.
  What is the correct method to override on form and put code there, so that the lines appear with form opening?</p>
  
  <p>Thanks.</p>
