Again, this is a brand new install from a download today of the latest version of Flash Builder. It contains only Flex 3.5 and 4.1.

I've set these values per instructions in OSMF 1.5 Release Notes s03.pdf:

• 4. Set Require Flash Player version to 10.0.0.
• *Flash Builder 4 users must change default SDK version to Flex 4.0 and check the “Use Flex 3 compatibility mode” checkbox to avoid compile errors.
• The Flex 4.0 SDK ships with an earlier version of OSMF. If you want to use the Flex 4 SDK with the latest version of OSMF, you need to remove the older version of OSMF. To do so in Flash Builder 4, select File > Properties > Flex Build Path > Library path, select osmf.swc under Flex 4.0 SDK on the Library Path panel, and click the Remove button.

What other information can I provide?

It is not, it's a normal flex app. I thought it might be because the projects were older ones and perhaps they pointed to some other playerglobal.swc in their .actionscriptProperties file, but I have created a new project and added simple code and I still see the same issue.

I've been able to reproduce quite quickly with a fresh install of Flex Builder.

1. Download the latest version of Flex Builder 4 for Mac
2. Create new project.
3. Follow instructions in OSMF 1.5 Sprint 3 Release Notes.pdf -
   1. Select the project folder and choose File > Properties. In the Properties window, select Flex Compiler.
   2. Verify the Flex SDK version. OSMF should work on any Flex SDK version, but the sample apps that we ship with may be created with Flex SDK 3.2 or above.
   3. Set Require Flash Player version to 10.0.0. In order to install/update Flash player, please go to
   4. Copy OSMF.swc on to your local machine.
   5. In your Properties window of your project, select the Flex Build Path ‐> Library Path tab
   6. Select Add SWC. Add OSMF and click Finish.
   7. Flash Builder 4 users must change default SDK version to Flex 4.0 and check the “Use Flex 3 compatibility mode” checkbox to avoid compile errors.
4. Use the following as application code:

<?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>

     <fx:Script>

          <![CDATA[

 

               import org.osmf.media.DefaultMediaFactory;

               import org.osmf.media.MediaFactory;

          

               var mediaFactory:MediaFactory = new DefaultMediaFactory()

 

          ]]>

     </fx:Script>

</s:Application>

When I try to compile this, I cannot because of the errors I've listed above. I'm using flex 4.1, and this happens regardless of how I set the compatibility mode. Thoughts?

Let me know if you need it in another format.

Thanks Ryan and Wei for the responses. I've attached a link to download the exported project in a comment above.

In the case of the project I sent, I have not messed with the flex sdk it uses, it's still set to the default for a new project that is set when you first in stall Flash Builder, which appears to be Use Default SDK (4.1).

Anything else I can do to assist?
