[Xsltforms-support] stepping through recordset type data display

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hello,

I have a specific problem where I wish to select a record from a 
xf:select1 list and then on on the basis of the selected value display a 
full record below it.

The full record will be displayed with the use of a xf:group tag, so I 
am a  really wanting to dynamically change the node the group references 
via its 'ref 'or 'bind' attribute.

I cannot get this to work, but I cannot find an example where someone 
has done this to know that it should work.

Effectively the behaviour that I want to replicate can be seen in an 
(non-Xform) example here 
http://xmljs.sourceforge.net/contributedAdd-ons/xpath/sampleApplications/contactManager/contactManager.html. 
This just steps through a xml 'recordset' displaying each record in 
turn. I'd be interested to see this done in an XSLTForms example!

My Xform code is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="forms/xsltforms/xsltforms.xsl" type="text/xsl"?>

        <br />
        <div id="console" style="display:block;top:100px;" />
    </body>
</html>

I want the output controls in the xf:group to change according to the 
item selected in the second select.

Interestingly the contents of the second xf:select1 changes 
automatically according to what is selected by the user in the first 
xf:select1 but the 'context' of the xf:group is not changing in the same 
fashion.

I can provide all the model data files as well if anyone is interested 
to see this in action.
