| 2 | This file demonstrates how the dojox.wire code can be used to do declarative |
|---|
| 3 | wiring of events. Specifically, it shows how you can publish and subscribe |
|---|
| 4 | to topics. In this case the setting of a value on one textbox triggers a |
|---|
| 5 | publish of that value to a topic. Another invoke is wired to fire when |
|---|
| 6 | values are published to that topic which is then displayed in another |
|---|
| 7 | textbox. |
