I've been reading on conversations and not sure if I'm getting it.

I have 3 selectOneMenu options A, B, and C.

A is populated when the page loads.

B is populated from a database query based on the selection of A.

C is populated from a database query based on the selection of B and only B, I don't need the selected value of A any longer.

Where if any are there conversations?  I'm added the @Begin and @End tags on the methods that populate the selectOneMenu lists.  Does the conversation Begin A - End C?  Are there 2 conversations, Begin A - End B and Begin B - End C?  Or perhaps only one conversation Begin B - End C?

Is conversation the way to go here, or perhaps just Session scope??

Thanks,
