I am using the APEX 4.2 mobile theme which has a "Select List" page item and where the "Page Action when Value Changed" is set to "Submit Page". The submit works when the values are in pull down but when the values come from popup window then it does not.
thanks for letting us know. It's a known issue (bug# 14680379) on our Known Issues List at http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-42-known-issues-1863578.html
