>runSheetDetails contains a list of all the Air Way Bills/Packages that need to be delivered. I am saving this list to localstorage in one process and then wanting to read it back from localstorage and display it on a web page. The initial save saves the entire list in one long string under one key (which I guess may be an array of arrays). When I read it back I get back that exact same long string. I want to process through that string and display each Air Way Bill on the page.

But is the 'runSheetDetail' parameter of saveLocal just one AWB or a collection of them? You're retrieving the content of the key (which is presumably an array of AWB's then *pushing* the parameter content. This will append if to the array. If it's a single item then that's fine - but, if it is an array then you would need to push each element individually. Hope that makes sense....

But if you are sure the content of the key that you pass to ko.ObservableArray is *exactly* the same as that obtained from the database then I don't know what to suggest - Knockout is not my subject :-{
