When I open the Flash Builder I am not able to toggle to the different views. I am only able to see the code version of the mobile app I am building. How do I turn this feature on?
The Design View was removed in FB 4.7. What version are you using?
There is no design view, so you have to run your program to see what will happen. You only have the code editor.
FlashBuilder 4.6 can co-exist alongside 4.7. Some folks use 4.6 for design view and 4.7 for other work. I think there are some gotchas arounds saving the project data from 4.7.
