-<!--
- This file demonstrates how the dojox.wire code can be used to do declarative
- wiring of events on one item to trigger event on other widgets. It also shows
- how you can use the Transfer object to morph data values from one format to
- another. In this specific case, it maps the values from a dojo.data Datastore
- item into values stored in a JavaScript Array, which is the format required for
- the addRow method of the demonstration TableContainer.
-
- Note that this demo expects dojo, digit, and dojox to all be peers in the same directory
- in order for it to execute.
