| 61 | This test makes sure that throwing an exception in the load callback will not stop further |
|---|
| 62 | dojo.io.bind() requests from proceeding. If <b>Error bind</b> is pressed, an exception |
|---|
| 63 | will be thrown in the load handler. <b>Safe bind</b> does not throw an error. In all cases, |
|---|
| 64 | the value of <b>testvar</b> should increase by 1 any time either button is pressed. |
