404 Error Generated When Opening a Taskflow as Popup (Doc ID 2007732.1)

Last updated on MARCH 16, 2021

Applies to:

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


A page opens a taskflow (using jsf pages, for navigation between pages) from another taskflow using fragments. When the popup appears, the content of the fragment is rendered before the page refreshes itself and shows a 404 not found.
If the browser is refreshed using f5, everything is fine and the issue is not seen anymore until the browser is closed.
Taskflows are defined in an external project and included as a .jar file (ADF Library) in the web app project.
This issue exists ONLY with IE, it works fine with Firefox and Chrome.

The feature was taken from this blog article: Reusable ADF Region with Dialog Framework
