Hi Alain,

Just had time to begin experimenting with the new methods you added.

I have tried:

<?xml-stylesheet href="xsltforms/xsltforms.xsl" type="text/xsl"?>
<html xmlns="http://www.w3.org/1999/xhtml"
     xmlns:ev="http://www.w3.org/2001/xml-events"
     xmlns:xf="http://www.w3.org/2002/xforms">
     <head>
         <title>4.8.1.a getInstanceDocument() method (non-normative)</ 
title>
         <xf:model id="my_model1">
             <xf:instance id="my_data1">
                 <car xmlns="">
                     <color>navy blue</color>
                     <new-color>pink</new-color>
                 </car>
             </xf:instance>

         </xf:model>
     </head>
     <body onload="f();">
         <div id="xformControl">
             <span>
                 <input type="checkbox"
                     onclick="$('console').style.display =  
this.checked? 'block' : 'none';"
                     checked="checked"/> Debug </span>
         </div>
         <xf:group>
             <xf:label class="title">4.8.1.a getInstanceDocument()  
method (non-normative)</xf:label>
         </xf:group>
         <xf:group>
             <xf:label>
                 This test case uses Javascript to execute the  
getInstanceDocument() method.
                 You may have seen a message box with the value  
&quot;<xf:output value="color"/>&quot;.
             </xf:label>
             <xf:input ref="color">
                 <xf:label>Colour</xf:label>
             </xf:input>

         </xf:group>

         <script type="text/javascript">
             function f() {
             try {

             var model = document.getElementById('my_model1');

             var inst1 = model.getInstanceDocument('my_data1');

             var my_color = inst1.getElementsByTagName('color')[0];
             var new_color = inst1.getElementsByTagName('new-color')[0];
             var old_node = my_color.firstChild
             var new_node = new_color.firstChild;

             alert(my_color.getTextContent());

             my_color.removeChild(old_node);
             my_color.appendChild(new_node);

             alert(my_color.getTextContent());

             model.rebuild();
             model.recalculate();
             model.revalidate();
             model.refresh();
             }
             catch(DOMException)	{
             alert('DOMException');
             }
             }
         </script>
         <div id="console" style="display: block"/>
     </body>
</html>

which attempts to replace one text value with another for the color  
element.

The values I get in the alerts suggest that removeChild and  
appendChild work, but the input bound to color continues to display  
the old value.

I also notice from the debug that the events raised by rebuild,  
recalculate, revalidate and refresh don't look right. I get:

Dispatching event xforms-recalculate on <SPAN class="xforms-model"  
id="my_model1"/>
0 -> Dispatching event xforms-revalidate on <SPAN class="xforms-model"  
id="my_model1"/>
2 -> Dispatching event xforms-refresh on <SPAN class="xforms-model"  
id="my_model1"/>
0 -> Dispatching event xforms-revalidate on <SPAN class="xforms-model"  
id="my_model1"/>
1 -> Dispatching event xforms-refresh on <SPAN class="xforms-model"  
id="my_model1"/>
0 -> Dispatching event xforms-refresh on <SPAN class="xforms-model"  
id="my_model1"/>

I am using build 241.

Here's hoping that I am just doing something wrong :-)

All the best

Mark
