WebPopUp problem: defaulting to Safari

In trying to implement a WebPopUp to send a tweet via Twitter intents, I’m finding that the first call when running the app on device to the WebPopUp loads mobile Safari rather than a WebPopUp window.

 native.showWebPopup(0, 20, display.contentWidth, display.contentHeight - 90, "http://twitter.com/intent/tweet?text=" .. message)  

I can actually see the WebPopUp open initially for a split second, then the activity indicator appears for a moment, before the app exits for Safari.

Subsequent calls work properly.

Is this a problem anyone else has dealt with? I saw in another thread that iOS 5 has very aggressive caching behavior. Is this a manifestation of this same problem? If so, has this been flagged in a bug report yet?

Well, it seems Daily Build 760 has resolved this. Thanks, Ansca. [import]uid: 1560 topic_id: 22786 reply_id: 91023[/import]
