AIR 3 Bug: PDF width is more than HTML width

Oct 17, 2011 7:38 AM

In AIR 3, I'm loading a PDF using the mx:HTML component. Here's some sample code:


<?xml version="1.0" encoding="utf-8"?>

<s:WindowedApplication xmlns:fx=""





<s:HorizontalLayout paddingBottom="8" paddingLeft="8" paddingRight="8" paddingTop="8"/>


<s:VGroup width="100%" height="100%">

<s:Button label="Open PDF" click="html.location = ',top'"/>

<s:DataGrid width="100%" height="100%"/>


<s:BorderContainer width="100%" height="100%" backgroundColor="#EFEFEF">

<mx:HTML id="html" width="100%" height="100%"/>




The HTML area has a width of 100% but only takes up half the screen due to another component which is also trying to use 100% of the screen. In AIR 2.x the PDF displays fine, but in AIR 3 the PDF displays as though it's using the.entire width of the runtime window instead of the HTML's width.


If the runtime window is resized, minimized or maximized, the PDF width automatically changes and matches the HTML width, which displays fine. This is the only workaround I have found that doesn't involve removing software from the workstation. Another user has found that downgrading from Acrobat 10.x to 9.x also works, but for Windows 7 users that have Acrobat 8 Pro and Reader 9 (like me) this causes errors (that are fixed in Reader 10), so this isn't a suitable workaround for me.


Here's the bug report:


Any chance this bug could be looked into urgently as it's preventing us from using AIR 3 or any Flex applications that use the AIR 3 SDK?
