title: APEX IG not rendering grid correctly
body: <p>I am trying to add a fixed check box to an IG.  They will be able to edit other fields but not the check box.  Here is the sql and result for the IG.</p>
  
  <pre><code>select CAR_ID,
     CAR_NAME,
     TOP_SPEED,
     TRAC_CTRL,
     DATE_SOLD,
     CASE
       WHEN DATE_SOLD is null
      then
         APEX_ITEM.CHECKBOX(1,1) 
      END "For Sale"
  </code></pre>
