title: Post query trigger not firing after LOV population in oracle forms 10g
body: <p>I have a master detail form in which details in a second block are displayed based on the first block.  The problem is, when i use a LOV selected value the post query trigger is not firing in the second block and i cannot understand why.  The relationship is set up correctly as records are correctly displayed when i navigate through them using the default keys on the form.  My code to open the LOV is as follows:</p>
  
  <pre><code>DECLARE
      SUCCESS BOOLEAN;
      BEGIN
      do_key('clear_form');
      SUCCESS := SHOW_LOV('STUDENT_LIST');
      set_item_property('registration.netid', property_true);
      END;
  </code></pre>
