af:showPrintablePageBehavior Fails Inside Form With usesUpload=true Defined In TaskFlow
Last updated on JULY 21, 2017
Applies to:Oracle JDeveloper - Version 220.127.116.11.0 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 18.104.22.168.0.
In ADF 22.214.171.124.0 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 126.96.36.199.0 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.
