Eclipse: how to change into the correct perspective automatically when editing a file?

Question

I want to configure Eclipse to change into the appropriate perspective automatically when I open a file for editing. For example if I am in Java perspective and open a MXML or ActionScript file then I want the perspective to change automatically to the FlashBuilder perspective . Then if I reopen the Java file for editing it should switch back to the Java perspective .

I think I remember seeing a prompt asking if this should be the default behavior when I first installed Eclipse, and now I wish I had accepted that. I can't find anything in the settings which allow me to configure this behavior. Is it possible, and if so how?

I am running Eclipse Helios Release 2 on a Windows machine.

Go to Preferences -> General -> Perspectives and then you have the option to "Open the associated perspective when creating a new project" set it to "Always open".
