Hi all,
a year ago, I developed a PyObjC application under Tiger that used
WebView to implement a kind of kiosk-system. Very simple, all in all 20
lines of actual code.
Now, on two Leopard-machines, the program stopped working. The behavior
is strange - the view simply stays blank.
I tried to re-implement the app with XCode 3.1 & it's new Python Cocoa
templates. No change.
Now I even created a ObjectiveC-app, see the code below.
This I see in the console:
12.01.09 22:21:10 WebKitTest[1305] awakeFromNib
12.01.09 22:21:11 WebKitTest[1305] gotoMain:
12.01.09 22:21:11 WebKitTest[1305] NSConcreteNotification 0x1172d0 {name
= WebProgressStartedNotification; object = <WebView: 0x129010>}
12.01.09 22:21:11 WebKitTest[1305] NSConcreteNotification 0x1172d0 {name
= WebProgressEstimateChangedNotification; object = <WebView: 0x129010>}
12.01.09 22:21:11 WebKitTest[1305] progress: 1.000000
12.01.09 22:21:11 WebKitTest[1305] NSConcreteNotification 0x1172d0 {name
= WebProgressFinishedNotification; object = <WebView: 0x129010>}
12.01.09 22:21:11 WebKitTest[1305] progress: 0.000000
So... it seems as if everything is working, just not the display itself :(
I'm pretty desperate here, as I need this App working till the end of
the week...
So *any* suggestions are more than welcome!

Diez B. Roggisch
