Each and Viewport : elements disapear

Bug Reports
1

Hi,

I ran into a problem with <Viewport>. Let’s create an Observable of a few items, and iterate with <Each> to display them… in a Viewport. Everything was fine until that 3 last words that makes our elements disappear.

EDIT : You need an Observable, it works fine with <Each Count="3">.

Test case :

MainView.ux

<App Theme="Basic" Background="#eeeeeeff">
    <JavaScript File="MainView.js" />
    <!-- <Viewport> Add this and break everything ! -->
        <StackPanel>
            <Each Items="{items}">
                <Rectangle Height="100" Width="100" Margin="10" Fill="#00f" />
            </Each>
        </StackPanel>
    <!-- </Viewport> -->
</App>

MainView.js

var Observable = require('FuseJS/Observable');

var items = Observable('a', 'b', 'c');

module.exports = {
    items: items
};

EDIT : Adding a <Panel> around each <Rectangle/> doesn’t fix it.

There seems to be an issue with layout invalidation. If you resize the window (or rotate device) the rectangles appear in the viewport.

I’ll create an issue for this and look to fix it.

I’ve fixed the issue. It’ll be available in an upcoming release.
