In your projects main view source, there should be a list of the views, you can just take out the one you don't want in to show up in the tabs listing.
Thats not what i was looking for...
I wanted to have the tabs show on different pages. For example, when i am on Page A, have the 'Page A' tab hidden. So if i have 5 pages in my app but only want 4 tabs and in order to get to the 5th page you would need to trigger something else.
I see. Check this post:
and the other parts to it. Im not sure if it can be done without some custom coding. I couldn't find a real easy way to do it anyway. But I am by no means an expert with Flash Builder. You could make your own "tab view" using buttons or other components also...
