Tabular form - Client side Clone Row on apex 4.1 not work

Question

Hi all,
j have a tabular form page where i have implemented Vika's clone row solution.
(See http://htmldb.oracle.com/pls/otn/f?p=24317:49)
Now, after migrating my application from Apex 3.2 to Apex 4.1 this feature not work.
Clicking the Copy icon copies the row and puts it right below.
Now, if I change some values in the new row and click Save, the MRU process updates does not insert the row in the database
Apex 4.1
rdbms 11.2.0.4
win xp
chrome browser
Any help?
Thanks in advance.

The "clone row" function is
</script>
     <style type="text/css">
     img.clone {
     cursor:pointer;
     </style>
     <script type="text/javascript">
     var g_this;
     function fn_delete(pThis)
     var l_tr=$x_UpTill(pThis,'TR');
     l_tr.parentNode.removeChild(l_tr);
     function fn_CloneRow(pThis){
          g_this=pThis;
          l_tr=$x_UpTill(pThis,'TR');
          l_table=$x_UpTill(l_tr,'TABLE');
          l_tbody=$x_UpTill(l_tr,'TBODY');
          l_clone=l_tr.cloneNode(true);
          html_RowHighlight(l_clone,"pink");
          l_inputs=l_clone.getElementsByTagName('input');
          for (var j=0;j<l_inputs.length;j++) {
          l_this=l_inputs[j];
          if (l_this.type=="hidden") l_this.value="";
          if (l_this.name=="fcs") l_this.value="zzzz";
          if (l_this.type=="checkbox") l_this.parentNode.removeChild(l_this);
          // Change Clone functionality to Delete
          var l_img=l_clone.getElementsByTagName('img')[0];
          l_img.src="/i/delete.gif";
          if (document.all) l_img.onclick=function(){fn_delete(this)};
          else l_img.setAttribute("onclick","fn_delete(this)");
          l_tbody.insertBefore(l_clone,l_tr.nextSibling?l_tr.nextSibling:l_tr);
     </script>

I have't looked at the specific clone-row sample code you mentioned in your post, but just wanted to point out that we've introduced client-side add-row functionality in APEX 4.0, so if you're using this code to add new rows on the client-side, then using the built-in functionality might be easier. Of course if you actually want to get a copy of an existing row, that might not be sufficient. As for the MRU process, the way APEX identifies new rows is by looking at the primary key or ROWID column value, which needs to be NULL. APEX also looks at the apex_application.g_fcud array, which holds information for each row on whether to do an create, update or delete. This array was introduced in APEX 4.0, and that's what could potentially be causing your example to fail after the upgrade.
