Going to some url when selection in combo box changes

[neman]

I'm trying to create a combo box in which are some urls and when user selects some String in this combo it automatically goes to that url.

Can this be done?

I was trying to do this with SimleComboBox and SelectionChangedListener but it doesn't work.

Many thanks! :)

Almost forgot. I'm using Gxt 1.2.4 :)
