[dart-misc] value of selected item in core menu in dart

[Mateusz Lewandowski]

Hi.
i have a problem with core-menu in dart.
I create polymer element with core menu

<polymer-element name="menu-element">
<template>
<core-menu selected="0" on-core-select="{{SelectItem}}">
<core-item icon="dialog" label="Ogłoszenia"></core-item>
<core-item icon="settings" label="Logowanie"></core-item>
<core-item icon="search" label="Rejestracja"></core-item>
</core-menu>
</template>
</polymer-element>


I need to send to SelectItem function, selected item in my menu.

Here is my code:


class Menu extends PolymerElement {
Menu.created() : super.created();

void SelectItem(dom.CustomEvent e)
{
var detail = new js.JsObject.fromBrowserObject(e)['detail'];
if(detail['isSelected']) {
// var item = (detail['item'] as CoreItem);
print(detail['item'].label);

}
}
}


My approach does not work and my question is, how to send selected item value to function?

Event bindings are without `{{}}` it should be

on-core-select="SelectItem">

Are you sure about that Gunter? This looks like Polymer 0.16, which would create event bindings using {{}}. I think we need further information, like what version of Polymer, what browsers you've tried this in, as in have you tried running it in Dartium, which I assume you have? And also any output in the browser console window would be useful.

It worked with {{}}
Yes it is Polymer 0.16
