Hi all,
First question here as I seem to be stuck. I have created a NestedList example that works fine on safari and chrome, but does not work on the iphone simulator or the iphone itself. Initially I had a version that worked with ajax and got the json dynamically, but even when I made a very simple version using local json data and the sencha css and js in the same directory it doesn't work on the iphone (simulator). To test it you can just start up the iphone simulator and drag & drop the html file on it. It will show the header and footer and also the title of the NestedList, but no data. No errors either. Any ideas? Can anybody confirm they have the same behaviour? As said, it works fine in safari, just not on the iphone or the simulator.
