I need to know how to trigger the update for an observableArray when an observable is changed inside the observableArray.
I have an observableArray that represents a binary tree. I'm using a storage mapping function to get and set the values in the array so it has to be balance even thought it might only contain an empty observable. E.g. nodes()[9] maybe null but when that node is updated I would call nodes()[9](set new value) and need to trigger the observableArray to update
回答1:
Ended up using .replace() on the observableArray
回答2:
Managed to look through the code and find observableArray.replace ()
