• Cross-platform modules: 3.0.0

• Plugin(s): -

Please tell us how to recreate the issue in as much detail as possible.

1. create default project with iOS platform(tns create..)
2. make a modal page like below and open it by tap event on 1st page

<StackLayout>
 <Label id=‘label1’ text=‘short’ textWrap=‘true’ />
 <Button button=‘label’ text=‘tap’ />
 <Label id=‘label2’ text=‘’ textWrap=‘true’ />
</StackLayout>

3. in modal pages tap handler, modify label1 or label2 text property to long text(like ‘foooooooooooooooooooo……’)

-> text will be not wrapped(label1) and text will not be shown (label2)

Besides this issue, I found that another UI has similar problem in modal page. such as Html or Image. when expanding height of these UI parts programmatically, no layout change happens.

When text or src or html property is bound to model. The behavior is same.This problem is very critical when bounded properties initial value is null. (Nothing shown when setting value.)

I checked same test on non modal page and seems ok. so the problem looks like modal page specific issue.
