Copying this question from the same forum, I have exactly this problem but couldn't find any help on this, maybe anyone else resolve it yet? I am testing it on Android Emulator and I am using Sencha Touch V1.
"I keep getting an error in my app, and I cann't find a solution.
My app also functions offline, so to get data to the app, it has a sync function. This is a series of looped functions, ajax requests and ended by inserting the data into stores and using them to fill panels.
This can be a lot of data, and resently when I was stress testing my app, I got the error "Execution Exceeded timeout" while I was trying to fill stores with the data and filling the panels with that data. The odd thing is that it that the error doesn't always occur on the same 'line'. I have been getting errrors from Sencha Touch debug line 6840, 12740, 13144, 22613, 1429, 1212 en 3195.
Does anyone know how to solve this problem? To maybe extend the time-out?
Any help would be appreciated"
