A remake of Frank's (Frank Nimphius) article How to auto-dismiss af:popup dialogs and the sample 105, a user on OTN JDev & ADF forum tried to get this running on JDeveloper 126.96.36.199.0. Franks sample was built using JDeveloper 188.8.131.52.0 and can't be run without changes in JDeveloper 184.108.40.206.0.
As it turned out there is a problem with the af:poll component and the timeout setting. This timeout setting should cancel the poll component after the given period of time (which should work in 220.127.116.11). This was one key feature in Frank's original article. Using 18.104.22.168.0 it turned out, that the af:poll remains active even after the timeout period should have canceled any further events to the poll listener.
The sample application for this can be loaed from http://java.net/projects/smuenchadf/sources/samples/content/BlogSelfClosingPopup.zip
A full description of the problem can be found at http://tompeez.wordpress.com/2013/03/24/jdeveloper-11-1-1-6-0-self-closing-popup/
A workaround for this is implemented in sample http://java.net/projects/smuenchadf/sources/samples/content/BlogSelfClosingPopup_v2.zip
