Newbie BSelect question

I have been trying to understand Barracuda with the view to apply it to 
building a fairly extensive web application (actually porting and expanding 
an existing application written ColdFusion / javascript / servlets). 
Barracuda seems very promising but daunting. I need help in order to grasp 
the basics.

For instance: I need to create a select element in an html page, which will 
allow the user to choose an action. In other words, selecting an option and 
then pressing a button will take the user to a page, according to which 
option was chosen.

Am I right in assuming that, since choosing the option happens on the client 
side, you have to define a form on the page and then either:
- define a javascript event handler on the button, that sets the form action 
according to the option chosen, and submits the form (this is what I would do 
spontaneously); or 
- submit the form and handle it completely on the server side (redirecting 
according to option chosen)?

If that is so, why is Barracuda offering the possibility to link a BAction to 
a BSelect, or the addEventListener() method on BSelect? What is the point in 
taking an action based on an event fired by BSelect, if you have no way of 
knowing which option was selected?

I know these sound like elementary questions, but I have put a lot of time 
trying to understand the components and especially their relationship with 
the event model. I have read the appropriate tutorials, as well as looked at 
the source code of the examples and of the components themselves.

As mentioned above I have experience with web appications and also with Swing, 
but none of that seems relevant here.

Perhaps I am missing something obvious... Could someone be kind enough to post 
relevant snippets of html and java code that would accomplish what I am 
describing?
