JSF/Rich Faces Drop down funtionality suggestion

Question

Hi friends,

I am using JSF/Rich Faces with Spring Webflow. I am implementing a functionality where in I have a drop down menu, where with each selection I need to trigger different transition in the webflow.

For Example I have a drop down with values [Admin, Home, Logout, Search]

On select of any of these items I should fire an appropriate transition from Spring webflow.

Eg:

<transition on="admin">

    <evaluate expression="testProgram.getAdminDetails" result="flowScope.adminList"/>
    <evaluate expression="testProgram.getUserInfo" result="flowScope.userInfo"/>

</tansition> 


<transition on="home">

    <evaluate expression="testProgram.clearMyInfo" />

</tansition> 

Here i have seperate transitions on for each of the menu items; how can I call appropriate transitions on select of a specific field from dropdown.

Thanks.
