We've started seeing strangeness with the popups in 2.4. Everything works fine for the first couple of clicks on a feature in a given layer. Then, all of a sudden, and without errors, the popup starts coming up blank. It's not always the same popup that is blank. I.e. a given feature is clicked, the popup shows correctly, then another feature is clicked and shows correctly. Then if you go back to the first feature that originally showed correctly and click, the popup comes up but doesn't show any of the fields. Also, once the blank popup comes up, all popups for that feature start showing blank as well. The only way that we get the fields back is to reload the page. Things will work fine for a while then all of a sudden, blank popups. This appears to only happen in 2.4 version of viewer. Using the same map services and config files works fine in 2.3 viewer. Any ideas what is going on? Any idea where I need to set a breakpoint in flash builder to try and isolate this issue? Any assistance would be greatly appreciated as we are about to go insane trying to track this down.
