YUI View - container attribute removes id

Post Posted: Thu Mar 29, 2012 6:34 pm

Hello,

I was testing out the YUI View component
Code:
Y.PieView = Y.Base.create('pieView', Y.View, [], {
    ...
}, {
    // Specify attributes and static properties for your View here.
    ATTRS: {
        // Override the default container attribute.
        container: {
            valueFn: function () {
                return Y.Node.create('<div id="pie"/>');
            }
        }
    }
});
and I ran into an issue. It seems that if I create a new div node in the container ATTR with an id, then when I try to get the container instance in the view's render(), then the id is no longer there
Code:
this.get('container').get('id')  // is empty string
Anyone else notice this?

Thanks

Daniel Ji

Can you point me to an example that reproduces this problem?

I tried out the code you have here and it worked correctly for me:

Hi Eric,

Thanks for the quick response! False alarm. I thought it was a bug possibly due to using a YUI View in a YUI custom module, but it is not. I'm trying out TDD and turns out I was initializing the view in the setup() of my test case with a config object
Code:
Y.myCustomViewModule({
container: '#someSelectorThatDoesNotExist'
});
So even though I redefined the container inside the View class definition, the container was getting overridden by the container selector defined in the config object at construction! Once, I got rid of that it all works.

Now that I think of it, I guess I took one too many leaps and not enough baby steps w/ TDD :)

Thanks for the support!

Oh good. That makes more sense that it wasn't working as expected because it was being overridden at the instance level.
