<nettprice/>
</LineItem>
</DPurchaseOrder>
</Body>
</Document>

<xforms:group>
<xforms:repeat id="repeat_lineitem" model="model_Document"
nodeset="/Document/Body/DPurchaseOrder/LineItem">

<xhtml:tr>
<xhtml:td><xforms:input ref="custcode" class="Product-Code"
/></xhtml:td>
<xhtml:td><xforms:input ref="suppcode" class="Product-Code"
/></xhtml:td>
<xhtml:td><xforms:input ref="quantity" class="Product-Quantity"
/></xhtml:td>
<xhtml:td><xforms:input ref="units" class="Product-Units"
/></xhtml:td>
<xhtml:td><xforms:input ref="unitprice" class="Product-Units"
/></xhtml:td>
</xhtml:tr>
<xhtml:tr>

Colin,

I assume you want to set a value in the newly inserted row? I think
the issue you are encountering is that the repeat index will change
upon insertion. Your code asks the XForms engine to insert an element
after the current element in the repetition. But the context for the
execution of the xforms:setvalue action is:

/Document/Body/DPurchaseOrder/LineItem"

This means that:

<xforms:setvalue ref="suppcode"></xforms:setvalue>

actually always refers to the "suppcode" element of the *first*
LineItem element, as per the XForms first-node rule.

What about writing, instead:

<xforms:setvalue ref="../LineItem[index('repeat_lineitem')]/suppcode"/>

Alternatively, you can create an insertion template that always
contain the default values:

<xforms:instance id="LineItem-template">
<LineItem>
<custcode>custcode</custcode>
<quantity/>
<suppcode/>
<units/>
<description/>
<unitprice/>
<nettprice/>
</LineItem>
</xforms:instance>

And then use the @origin attribute on xforms:insert:

<xforms:insert at="index('repeat_lineitem')"
ev:event="DOMActivate"
nodeset="/Document/Body/DPurchaseOrder/LineItem"
position="after"
origin="instance('LineItem-template')"/>

try this:

<xforms: instance id="document">
<Document>
    <Body>
      <DPurchaseOrder>
        <LineItem>
          <custcode>custcode</custcode>
          <quantity/>
          <suppcode/>
          <units/>
          <description/>
          <unitprice/>
          <nettprice/>
        </LineItem>
      </DPurchaseOrder>
    </Body>
</Document>

....

<xforms:group>
<xhtml:table>
    <xforms:repeat id="repeat_lineitem" nodeset="instance('document')/Body/DPurchaseOrder/LineItem">
      <xhtml:tr>

        <xhtml:td><xforms:input ref="suppcode"/></xhtml:td>
        <xhtml:td><xforms:input ref="quantity"/></xhtml:td>

        <xhtml:td>Net Cost</xhtml:td>
        <xhtml:td><xforms:input ref="nettprice"/></xhtml:td>
      </xhtml:tr>
    </xforms:repeat>
</xhtml:table>
</xforms:group>

<xforms:group>
<xforms:trigger>
    <xforms:label>Add Line Item</xforms:label>
    <xforms:insert at="index('repeat_lineitem')"
                   ev:event="DOMActivate"
                   nodeset="instance('document')/Body/DPurchaseOrder/LineItem"
                   position="after" />
    
    
    <xforms:setvalue ref="suppcode"></xforms:setvalue>
    
    
    <xforms:setvalue ref="index('repeat_lineitem')/suppcode"></xforms:setvalue>
</xforms:trigger>
</xforms:group>

Hope that helps.

Henrik

PS! Next time, attach an xforms source file that will run / won't run in the XForms sandbox on orbeon.com. It's much easier to help.
