in Vinson how do I access the child view Item.Price from within the ItemDetails.View?

Do you have a sandbox site where this is running? I can go there and look at your ItemDetails.View and see if I know the answer.

I don't have Vinson code to look it up...

<@U6HNETRC1> Do you have a `ProductDetails.Base.View` in Vinson?

Disable the qty input as I am working on a calculator for the qty

Like fire an event to that disables and re-enables later?

Or just set the qty input element to disabled all the time.

disable the input if a custom checkbox field is checked

So you need a backbone event in that view. What is the custom checkbox element id?

the checkbox is not exposed in the UI, just a flag to trigger my calculator

Oh, it's driven from the back end... gotcha.

I would put this in the Item.Price (or whatever that's named in Vinson) initialize method.

Yea.. was trying to use getChildViewInstance(‘Item.Price’) but that doesn’t seem to work

The "don't do this" section should be helpful for Vinson.

Wrap or extend the initialize method. You can also add to the events object if you need to include user input.

```ItemDetail.prototype.initialize = _.wrap(ItemDetail.prototype.initialize, function (fn) {
	var context = fn.apply(this, _.toArray(arguments).slice(1));
	// do your stuff here....
});```

You know when you are so focused on doing something a certain way…

 That most obvious and simply way, that you are already using for another view, is overlooked.:headbang:
