I've two dropdowns on my jsf page.
I want to change the values of second one based on the value selected in the first. So once the user selects some values in dropdown 1 the values in dropdown 2 should be refetched.
How to do this?

You should be able to achieve this w/ PartialTriggers (FYI, I use Apache Trinidad). Here is a snippet of my JSF code:

First ListBox:

Second ListBox:

Notice the second listbox: I have the partialTriggers attribute set to the id of the first listbox and in the backing bean whenever the user selects a value in the first listbox, this valuechange is captured and sent to populate the second box.

Hope this helps.
