Question

I’m totally new to flex and tried to create helloWorld app unsuccessfully.
Steps:

1) Create flex project within flash builder;
2) Added <s:Label text="Hello World" x="100" y="100" /> to HelloWorld.mxml file in default package;
3) runned project with Flash Builder;
4) saw an empty flash page in browser window;

Did I miss something?

HelloWorld.mxml:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
           xmlns:s="library://ns.adobe.com/flex/spark" 
           xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<s:Label text="Hello World" x="100" y="100" />
</s:Application>

P.S.
– Flash Builder 4.6;
– SDK 4.5.1;
– Other flash page do work correctly in browser (Chrome);

Ok, reposted from comment.

1. Did you try to open this swf in different browser?

2. Make sure to clear browser cache when your swf is not opened anywhere, and you
   can try to delete files manually.

3. Sometimes it’s easy to forget to save edited file, this isn’t your case, is it?

4. Reliable approach to
   see if your swf is updated or not is to Alert.show(‘version’) or to
   draw big red line across your app with graphics.
