Automatic App Refreshes

The requirements to support automatic refreshes for a custom app are identical to the requiredments for user-initiated refreshes with one exception:

The custom app class must implement the onRefresh() method just the same as for user-initiated refreshes. For this example, see Initial Render and Refresh Methods.

The App Specification, however, must identify the time interval to use for automatic refreshes in the refreshinterval attribute on the <app> element. This attribute identifies the time interval as a number of seconds which must be at least 5 seconds.

<app id="refreshTest" jsclass="Sample.RefreshTest" name="refreshTest"
minimizable="false" draggable="false" height="auto" width="auto"
refreshinterval="10" >
