Alex pointed out that there appeared to be multiple updates of the tileList dataProvider.
I did some digging and indeed there were duplicated httpservice calls to populate the tileList. One from the creationComplete event and another from a 'show' event. The result was that there were 2 rapid-fire successive calls to update the dataProvider. Apparently this created a problem with the indexing of the list items creating all kinds of havoc. drag and drop did not work - clicking an item would not produce a 'selection' or create selectedItem..... what a mess Once I removed the duplication the tileList performs totally as expected. Thanks for the keen eye Alex !
