I have an app that has several different pages that use Sencha Touch. Ocassionally the app switchers between those pages via a window.location call. When it does, on the iPhone (but not in Chrome or on Androids), I see a lowercase t in the upper right hand corner for a minute before the page rendering completes.
Has anyone seen this? Or does anyone have any idea on how to track down the cause of this? I initially suspected that there might be an errant character on my pages, but I have checked them all carefully and don’t see anything that could cause that. I now suspect that it may be a Sencha bug, but I don’t see any way to track it down since it only occurs on the iPhone.
This turned out to be coming from jQuery (yes, I was using both jQuery and Sencha Touch) – I don’t know whether jQuery was having an issue with Sencha, or whether it was just a bug, but after upgrading to jQuery 1.6.2, the problem resolved. Also, if I removed all references to jQuery from my project, the problem resolved.
