| 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. |
