I have one search input field and several search initiation buttons, 
each triggering a different kind of search. Normally I would have the 
button handler find the search input field by name and get its value and 
send that to the server. But I just spent over an hour scanning the doc 
and cannot find anything close, or even how I would give a widget a 
name. In HTML this is getElementById, of course, working with the ID 
attribute.

Another way for me to go would be to have the containing chunk of the 
framework have an element "searchValue" and then have both the search 
input field and buttons (a) look for the designated ascendant by type 
(say, "SearchPanel") and then take the searchValue element from that. 
But then I am not sure how to do that either. In other threads I learned 
I should use getLayoutParent to navigate up the hierarchy, but neither 
did I see a way to test an object's class.

I will be diving into the source code, but hints are welcome.

cheers, kenny
