XForms/Insert with Origin

Motivation

You want to insert new values into an instance of the model and specify where to find the initial values of the insert.

Method

You can add an origin attribute to the insert statement to tell XForms where to get the initial data for the insert. This is the preferred method over doing many setvalues. The syntax of the insert is the following:

<xf:insert ev:event="DOMActivate" 
   nodeset="instance('persons')/Person"
   at="last()" position="after"
   origin="instance('init')/Person"/>

Screen Image

A sample screen image. Many people do not have the ability to run the examples so this is critical.

Use this format:

This is my caption
