Flex - changes to mxml not reflected in browser

I have a Flex project and am using a trial version of Adobe Flex Builder 3 to build it.

I do the following: 1. Change an mxml file in the project (for simplicity, assume I changed the text in a label). 2. Right click on the project, Export, Release Build开发者_如何学Python 3. Right click on the main mxml file, Run As -> Flex Application

A browser window opens, everything runs fine, but I cannot see the change I made in step 1.

I thought the browser (tried with IE, Chrome) might be caching stuff, so I tried after deleting all temporary internet files, but I see the same behavior.

Am I being dumb and missing something or is there something going on here?

Check the timestamp on your .swf in your release folder. You might be running from a different folder.

Check the URL of the flex app in your browser to see if its running the debug version or the release version.

file:///C:/ASWorkspace/FlexTest/bin-debug/FlexTest.html

When you run a flex app, flex builder normally runs the debug version. Exporting the release build is done when the project is completed - release build won't have any debug information in it and hence will be compact. If you have selected Build Automatically in the Project menu, the debug version will be recompiled automatically when you save a file. You can just hit F11 to run it.
