title: oracle forms. child form doesn't see main form posted changes
body: <p>I have a trouble with oracle forms. The scenario is:</p>
  
  <ol>
  <li><p>There is main form with a data block that contains records from TABLE_A.</p></li>
  <li><p>User selects a record in data block then press button "Generate details", at that moment records in TABLE_B are generated for the master record in TABLE_A.</p></li>
  <li><p>User press button "Details", the next code is executed:</p></li>
  </ol>
  
  <pre><code>    DECLARE
        L_Item item_master.item%TYPE;
        L_pl_id PARAMLIST;
      BEGIN
        Post;
        P_Destroy_Parameter_List('RTVDTL');
        L_pl_id := Create_Parameter_List('RTVDTL');
        L_Item := :B_RTV_DETAIL.Item;
        Add_Parameter(L_pl_id, 'PM_RTV_ORDER_NO', Text_Parameter, To_Char(:B_RTV_HEAD.Rtv_Order_no));
        Add_Parameter(L_pl_id, 'PM_ITEM', Text_Parameter, To_Char(L_Item));
        --Open_Form('xxlmrtvdetail', ACTIVATE, No_Session, L_pl_id);  
        Call_Form('xxlmrtvdetail', No_Hide, No_Replace, No_Query_Only, No_Share_Library_Data);
      END;
  </code></pre>
  
  <ol start="4">
  <li>Detail form is opened, but there are no any records in data block that is linked to the detail table.</li>
  </ol>
  
  <p>If I comment row with "Call_Form" function and uncomment "Open_Form" the data is shown. Also, if I change "Post" with "Commit", the data is shown. It seems that child form is using the other session. Does some one know what could be the reason of the problem and how to fix it?</p>
  
  <p>Thanks!</p>
