hey ho, i think i havnt understand the complete angular2 construct, but my
problem is:
i want to create a simple angular2 app. based on some configs, there should
create some list containers, in any list container are some items. so, my
problem is, if i create a new list container (aka component):
c = new FlowList();
c.addItem(new FlowListItem('foo'));
c.addItem(new FlowListItem('bar'));
there will be add some items into a internal array of "FlowList".
@Component({
selector: 'flow-list',
directives: [FlowListItemRenderer],
template: `
<div class="flow-list">
<div class="elements">
<div class="element" *ngFor="#item of items">
<h2>Item</h2>
<flow-list-item-renderer
[_item]="item"></flow-list-item-renderer>
</div>
</div>
</div>
`
})
export class FlowList {
protected _storage:FlowListItem[] = [];
public addItem(item:FlowListItem) {
this._storage.push(item);
return this;
}
get items():FlowListItem[] {
return this._storage;
}
}
on adding point, there are all new items available. but on rendering, the
getter "items" return an empty array??? this is what i doesnt understand???
on the other side, if i create an storage service and inject it to my ListCmp,
all works as expected... but that isnt a option for me, in the end, there
should it possible to push items between all the lists. every list has its own
logic on receiving or pushing elemnts too (REST callbacks, different item
renderer components and so on...).
how can handle this? i think this is more a "best practise" question...
thx for any response!
