Using JSF 2.x ,how to update other UI components from a change in current component

Question

I have a selectOneMenu and below it I have a selectManyListbox . Based on what user has selected in selectOneMenu , I want to refresh selectManyListbox . Like for example say selectOneMenu has list of Students and selectManyListbox has list of Courses. So for example in this scenario, say if I select Student1 then automatically selectManyListbox should show Course1, Course9 as selected. If I change selectOneMenu to student2 then accordingly selectManyListbox should show his courses as selected ones. What would be the general strategy of doing this?.

Thanks!. This one matches my use case exactly. – user1525825 Sep 30 '15 at 08:20 — user1525825, Sep 30 '15 at 08:20

You could fire a change in selectOneMenu and fill the selectManyListBox's value.

<f:ajax event="change"/>

or if you are using primefaces, you could use <p:ajax event="change"/>
