Hey folks, Working on a problem I'm betting there's no solution for.
I've got an .swf embedded in a page which exposes several methods using ExternalInterface.addCallback(...), all of which return values. The problem comes in when I return an empty string "". Empty strings are converted to the string "null" (not even the JavaScript value null, an actual string). I could easily solve this in JavaScript by evaluating against "null", but unfortunately I'm writing the .swf to a spec which says that the .swf must return an empty string as a part of an error condition. In googling around, I've found a couple mentions of this problem, both on Adobe's site. The Flash Player 9 Release notes lists "Empty strings passed through External Interface API via JavaScript are converted to null. (184474)" as a known issue, and a user on LiveDocs lists this as a problem with the "internal serializer". What I'm wondering is if there's a work around that can be accomplished within flash. The only other solution I can come up with is to wrap my .swf in a JS object that'll evaluate against "null" and return "", but that seems a serious waste. Anyone have a clue? _______________________________________________ [email protected] To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
