Creating Dynamic Links using XForms

Hi,
Following is my use case:

- A servlet is returning file names and corresponding URLs in form of XML.
- It is being displayed on the form using a repeater control.
- XForms trigger with minimal appearance and XForms load are used to display
the result in form of likns.

The problem is that the link is not dynamic. All the links are opening the URL
of the first link only.

How can I resolve this issue?

Following is the code snippet....
<fr:td>
<xforms:trigger submission="replace-form-with" appearance="minimal">
<xforms:label>
<xforms:output ref="name" />
</xforms:label>
<xforms:action ev:event="DOMActivate">
<xforms:setvalue ref="instance('URL-container')"
value="instance('searchResult')//file/url" />
<xforms:load ref="instance('searchResult')//file/url" />
</xforms:action>
</xforms:trigger>
</fr:td>

Used following example for reference:

Regards,
Kamlesh

I think the 'value' of the shown 'setvalue' element needs to reference  
the specific repeated element within your search results using index()  
with the id of your repeat. Otherwise, the current  
instance('searchResult')//file/url will have the entire set of data be  
converted to a single node (the first item). Maybe try this for your  
'setvalue' element (inserting the id of your repeat element  
appropriately since I do not see your repeat in your code snippet:

xforms:setvalue ref="instance('URL-container')"
value="instance('searchResult')/file[index('IDOFYOURREPEAT')]/url" />

this seems to match the example you pointed to at http://en.wikibooks.org/wiki/XForms/Output_and_Links 
:

<xf:setvalue ref="instance('URL-container')" value="concat('http://en.wikipedia.org/wiki/' 
, instance('links')/link[index('link-repeat')]/wikipedia-id)" />

I am not sure about the need for the double-slash before 'file/url' in  
your snippet either. You might try that as either single or double to  
see what works.

Good Luck,

-Michael
