Maybe I'm missing something, but when you say reloadData, the *next* line is not executed until the data have been reloaded. So now you can select the previously selected item. The TidBITS News app does this, for example, and it's as simple as that: after I reload the data, I look to see whether there was a selection index saved off in the user defaults, and if there was, I select it. Of course I also remove that info from the user defaults so this won't happen again later as the app continues to run and the data gets reloaded again. t. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
