   This is crucial to how my apps work when users change tabs. Since a few of the tabs use the same code in different contexts - eg: twitter timelines for friends, mentions, favorites etc. I suppose I could code around it for now and use copies of various scripts.

   Any idea when this might get addressed?

   It's a bit of a showstopper.

   Hi,

   Try this: http://pastie.org/1035404">http://pastie.org/1035404

   It contains the JS required for app.js and test.js - for a simple test

   The use case for this is for (example) a Twitter client, where each tab is used for the list of tweets.
   They all the use same functions based in app.js but with differnt contexts and 'request_type' (eg: friends, mentions, favorites, etc.) - The API requests and all the tableView building all uses functions in app.js too.

   It seems that Ti on Android does not support the Window focus event which I use to see if the user has changed tab (and if it needs to request more data etc) and also it seems that it also does not support the ability for me to attach the name of the function in app.js as a window property when I build it - which works fine in iOS.

   Hope this helps! ;)

   Hi

   The window focus and blur events are crucial for us!

   We use the window blur event to cancel pending asynchronous HTTP requests that we don't wish to continue when the user selects another tab bar option, for example.

   Thanks

   Hi,

   I just noticed that it does not work in 1.3.2, too. We want to use the 'blur' to open a specific window cause we do not want to display the previous opened window when the user presses the back button.

   Hope this will be fixed/implemented soon.

   Thanks

   This issue is still broken in 1.6.1
   Tried the same code as copied from http://pastie.org/1035404">http://pastie.org/1035404.
   This is the output when switching between the windows.
