Active Data Service Channel Is Closed When Escape Key is Pressed (Doc ID 1533567.1)

Last updated on AUGUST 05, 2016

Applies to:

Oracle JDeveloper - Version 11.1.1.6.0 and later
Information in this document applies to any platform.

Symptoms

An ADF application uses Active Data Service to push data changes to the browser without specific user intervention. When the Web browser is Microsoft Internet Explorer, pressing 'Escape' while the page element is refreshing will break the data connection to the server, and no further updates will be seen. If the updates are very frequent, then the likelihood of the users hitting Escape at just the wrong time is particularly high.

This problem has been seen on JDeveloper 11.1.1.6 and 11.1.2.3, but most likely other versions are affected. It is likely that other browsers besides Microsoft's will also show the problem, but it seems to be harder to reproduce with FireFox..

The problem is only seen when the ADF channel mode is 'streaming', but this is the default.
