I have a perfectly running APEX application. For some testing purpose I exported the application and again "Imported" the application in same server.
But in the new application, POPup KEY LOV stopped working, i.e. if I press popup lov icon nothing appears, only "#" gets added to URL.
But the strange thing is If I create new page and use some POPup Key lov item then, it works fine.
APEX Version : 4.2.1.00.08
Theme : Theme 23 (Uniframe 23)
