How to write to a component from View to another in Perspective?

Hi there,

I have a header view with a dropdown. When the user selects a value from the dropdown i want to write that value into a Label component of a different view. What is the best way to do that?

You can use a tag or a perspective message

Edit: oops, I meant to come back and add to this, looks like Phil beat me to it though

Or bidirectionally bound session properties, or bidirectional view parameters bound to a custom prop in an outer view.
