Accessing Orbeon's second xforms instance

Question

Following Orbeon documentation about running xforms-with-java-applications, I deployed Orbeon's war file separately beside my java war on JBoss.

I tried creating 2 instances inside one model

<xforms:model id="fr-form-model">


  <xforms:instance id="don-instance1">
    <don>
     <laptop>                   
 </laptop>
    </don>
  </xforms:instance> 

  <xforms:instance id="don-instance2">
    <don2>
       <laptop2>                    
   </laptop2>
    </don2>
  </xforms:instance>

</xforms:model id="fr-form-model">

I can't seem to access the second xforms instance from the

<xforms:input ref="instance('don-instance')/don/laptop2">
   <xforms:label>Enter a Name:</xforms:label>   
</xforms:input>

Accessing the first xforms instance is fine, as long as I DON'T use the instance() function

<xforms:input ref="/don/laptop">
   <xforms:label>Enter a Name:</xforms:label>    
</xforms:input>

Somehow the instance() method isn't working as I expect, What am I missing ?

Answer 1

As per the code, i see that you are not referring the node names properly. If you want to access the laptop node in first instance then your code should be like this:

<xforms:input ref="instance('don-instance1')/laptop">
   <xforms:label>Enter a Name:</xforms:label>   
</xforms:input>

Same way, if you want to access the node in second instance, it should be

<xforms:input ref="instance('don-instance2')/laptop2">
   <xforms:label>Enter a Name:</xforms:label>   
</xforms:input>
