I am developing a plug-in in OEM and I have successfully deployed a sample plug-in by altering DemoHost plugin(Using Flex Builder). Now whenever I have modified some code or done some alignment changes or any small changes, then I completely undeploy the existing one and then redeploy new one from scratch. I have read in the document that it is possible to debug the application using Flex once the plug-in is deployed. But when I run the plug-in from Flex, it shows the login screen and even if I have provide the correct credentials, its throwing some error.
I am using Windows 7 as the development machine with Adobe Flex Builder 3 as development tool.
To run from FlashBuilder (or FlexBuilder) you need to either change your OMS to allow http access and select "http" from the login dialog that appears when running from FB. Or, you need to accept and install the security certificate in the browser you launch from FB. Please see this thread for details on how to accept the EM root certificate if you are not familiar with it. Re: A very important question about the HostSample-Help needed!
If this is not working for you then please post more details on exactly what error you are seeing when you attempt to run from FB.
Yes, it's possible to use breakpoints in your Flex project. Without more details, it's difficult to say what is causing your problem. Off the top of my head, a few simple things you can try would be to clear your browser cache, clean and rebuild your project, and verify you are starting your project using 'Debug' rather than 'Run'.
