Creating an extended ListItem class

I'm trying to create a replacement ListItem class, which I'm specifying with the createItem element of the delegate map. I've almost got it working, but I am forced to specifically call two of the properties "label" and "icon" instead of "title" and "image1" that I'd like for them to be, and I can't figure out how to do the binding for any other properties in the replacement class.

This is a stripped-down playground example where I have only three fields being displayed: title (which must be called label), image1 (which must be called icon), and numLikes. As you can see, the numLikes field displays its initial value ("wrong") instead of the value in the model. I'm probably missing a single line of code that would add all of the proper bindings, but I can't figure out what it is. Help greatly appreciated!

Here's the playground sample: http://tinyurl.com/78tfzdz

Thanks!

Re: Creating an extended ListItem class

Hi Derrell,

It is a pleasure for me to be able to help you for the first time as an official 1und1 member. I hope my hints will be useful for you. But first here it goes to the modified playground: http://tinyurl.com/7owlrsy

As you can see, you did all right, but you can use bindItems to bind any model property with your custom widget. Second, it’s necessary to name events of bindable properties always including his name e.g.

icon :

{

init : null,

check : “String”,

event : “changeIcon”

}

I hope, I could you help a little.

Regards Mustafa Sak

Congratulations! Welcome! It's great to have you there.

Fabulous. I knew there was something simple I was overlooking. That got me past that issue, and I'm now seeing a related but different problem, but I'll look into it myself before asking questions.

As you can see, you did all right, but you can use bindItems to bind any model property with your custom widget. Second, it’s necessary to name events of bindable properties always including his name e.g.

icon :

{

                init : null,

                check : “String”,

                event : “changeIcon”

}

Yes, that makes sense, based on the way it gets called. I'm also now able to call them by "title" and "image1" instead of by "label" and "icon", so I have no need to name them other than what they're supposed to be.

Thanks for the quick response!
