Hi,

when we have a `PageControl` whose pages are dynamic (with `Each`) and a binding for the Active page, the apps fails with :

`Fuse.Controls.Page already has a parent`

Here is my code :

MainView.ux

```auto
<App Theme="Basic" Background="#eeeeeeff">
    <JavaScript File="MainView.js" />
    <DockPanel>
        <PageControl Active="{currentPage}">
            <Each Items="{pages}">
                <Page Name="{name}">
                    <Rectangle>
                        <Text Value="{name}" />
                    </Rectangle>
                </Page>
            </Each>
        </PageControl>
    </DockPanel>
</App>
`

```

MainView.js

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

var pages = Observable();
pages.add({
    name: 'page1'
});
pages.add({
    name: 'page2'
});
pages.add({
    name: 'page3'
});

var currentPage = Observable('page2');

module.exports = {
    pages: pages,
    currentPage: currentPage
};

```

A possible workaround is :

```auto
var currentPage = Observable();

setTimeout(function() {
    currentPage.value = 'page2'
}, 1000);

```

but it easily becomes very tricky when the app is a little more complex.

Thanks !

We’ve found a race condition, and it will be fixed in an upcoming release.

Thanks again for the test case, which made the problem easy to isolate 🙂
