af:showPrintablePageBehavior Fails Inside Form With usesUpload=true Defined In TaskFlow (Doc ID 2287664.1)

Last updated on OCTOBER 25, 2022

Applies to:

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


Component af:showPrintablePageBehavior fails when inside a form with usesUpload=true defined in a view accessible from a task flow.
Instead of showing printable page, it shows a 404 error page.

However, this component works fine when usesUpload=false.

This issue happens in
In ADF the showPrintablePageBehavior works with usesUpload=true or false.

It was noticed that:
* the enctype of the form is set to "multipart/form-data"
* parameter "Adf-Window-ID" is being passed twice when "usesUpload=true": as url query parameter and in the post data (both have same value) . When using "usesUpload=false" it is only passed once as post parameter.

In order to reproduce the problem, just create on JDeveloper Suite an "ADF Fusion Web Application" adding a task flow and a view. In the view add a form setting usesUpload to true and label and a button with af:showPrintablePageBehavior.
