I solve the problem.
My select is in the component that i update, and this is the problem.
I put mySelection and myForm outside the [EMAIL PROTECTED], and it works.
With this solution i can easily get the value selected.
remarks : on my side, when i use targets instead of elements, it doesn't
work.
