Apex in iframe broken in 4.1?
Olafur TAug 30 2011 — edited Aug 24 2013Hi,
I am experiencing a strange problem after I upgraded Application Express to 4.1.
Every new application I create, will not work in an iframe. The frame shows up as empty (with chrome's element inspector showing the content as simply <html><head></head><body></body></html>
But older applications (created in 4.0 and earlier) they show up fine without problems.
I have tried all the themes in 4.1 they all do not work in an iframe and if I create new pages in an older application the new pages work fine in an iframe.
So there is some change in the 4.1 that seems to be breaking apex apps within iframes.
I looked at the sequence of events in the Chrome Network tab of the Developer Tools. I see a request for "f" with a response of "302" (temporarily moved), which is fine, its the session mechanism redirecting.
Then I see another request for "f" which gets the response of "Canceled".
I can get an apex error message to show by pointing to a non-existing page in a new 4.1 app, but that is the only response I have been able to get..
Any ideas anyone?
