I have two dropdown components. I need to set values in several other components depending on the values selected in two dropdowns. When a value is selected in the first dropdown, the second dropdown is populated and upon selecting a value in the second dropdown the values in the other conponents should be changed. But, when there is only one value in a dropdown change event does not occur. How can I solve this problem please?

Than you.

i don't think it's a JSF problem. all you have to do is to add a blank choice in addition to your unique value and set the dropdown list default value to blank. by this way, the user is obliged to select the unique choice by changing the blank value hence creates an event.
