title: ApEx 19.1 form region item value not passing on insert/create
body: <p>I've been designing a new app in ApEx 19.1 and one of the form/reports which I have created will not save a specific column when I click CREATE (SQL Insert action). Debug data shows that the data is in the session state when the CREATE request is being processed. I have verified that the value is not inserted with the other columns by querying the table in SQL Developer.</p>
  
  <p>When I click to edit the item, the page item is blank and the value is not in the session state. I can then choose a value, and it saves correctly (SQL Update action).</p>
  
  <p>I have several other 19.1 form/reports in the app which do not have this problem.</p>
  
  <p>Details:</p>
  
  <p>-ApEx 19.1</p>
  
  <p>-Modal Form page on an Interactive Report</p>
  
  <p>-New Form Region, not legacy DML setup</p>
  
  <p>-DATETIME column type, Date Picker item type
  -Required column, Value Required = Yes (and errors occur correctly if left blank)</p>
  
  <p>-The biggest difference between this page and others is that rather than navigating directly from the report page to this form dialog on Create, there is a different modal dialog form that must be filled, and then the user navigates to the form in question.</p>
  
  <p>All of the other fields insert data correctly to their corresponding columns, and I haven't changed any of the Source settings after creation, so I'm not sure what is causing the issue. I've even deleted the pages and rebuilt them with the same results.</p>
