> ScrollableStageText with large y value crashes app
> --------------------------------------------------
>
> Key: FLEX-34391
> URL: https://issues.apache.org/jira/browse/FLEX-34391
> Project: Apache Flex
> Issue Type: Bug
> Components: Mobile: ScrollableStageText
> Affects Versions: Apache Flex 4.12.1
> Environment: All
> Reporter: Colin Childs
> Assignee: OmPrakash Muppirala
> Priority: Critical
> Labels: ScrollableStageText, easytest
> Attachments: ScrollableStageTextTest.fxp

> When calculating the global viewport during the initial layout of a
> ScrollableStageText component, the y value can exceed the maximum allowed y
> value of StageText, causing the app to crash. The exact y value required to
> crash it varies based on scale, but globally, 8192 is the breaking point.
> This became an issue for me when placing user generated content with text
> inputs within a scroller.
> To replicate:
> 1) Create a new application
> 2) Place a TextInput control inside the view with a large y value (~10,000)
> 3) Run the app and see it crash
> I have included a sample mobile application that demonstrates this issue and
> a workaround I used to fix it. As a workaround, I extend ScrollableStageText
> and override getGlobalViewPort, setting the y value to the min of the
> globalRect.y and stage.stageHeight, and the same for the x value as well.
> This issue is also reproduced in the case:
> <s:VGroup>
> <s:TextInput width="250" height="190" text="One"/>
> <s:TextInput width="250" height="190" text="Two"/>
> .
> //Large number of text inputs (25+ depending on the size of the device)
> .
> <s:TextInput width="250" height="190" text="Twenty Eight"/>
> </s:VGroup>*
