Question

I’m having issues with multiple observableArray and adding/remove items with them in one view model.

The scenario is basically a contact management form, so I’m trying to allow them to enter multiple email addresses/telephone numbers etc.

Here is a test case:

Try adding a few emails and telephone numbers till the error happens.

If it helps, I’m on Firefox 12.

I based my code on this sample on the knockout website:

You forgot var self = this; in telephone and email definition. Fixed jsfiddle example here:
