title: Item values not displaying in Oracle Apex 4.2
body: <p><br>
  What on earth can cause that in an Oracle Apex 4.2 application, the item values are not displaying (display only, select list and text items), though I can check that they are correctly set in the Session State.<br>I initialize them in an After Header process, where I insert them into a database table as well, just for the sake of checking, and they appear correctly in the table...<br><br>
  Any idea?</p>
