http://code.google.com/p/moose-technology/issues/detail?id=510
We should be able to set the value of a port only temporarily. This would  
be useful for triggering other transmissions. For example, to implement a  
search like behavior we could use the code from below. The problem is that  
if you press the search icon once, then change the selection manually, and  
then press the button again, the selection will not change because the  
#focusOne port did not change the value.
|browser |
    browser := GLMTabulator new.
    browser act: [:b | (b pane port: #focusOne) value: 3 ] icon: MooseIcons  
mooseSearch entitled: 'Search'.
    browser column: #one; column: #two.
    browser transmit to: #one; andShow: [ :a |
    	a tree
    		display: [:x | 1 to: x]].
    browser transmit to: #two; from: #one; andShow: [ :a |
    	a tree
    		display: [:x | 1 to: x*2]].
    browser transmit to: #one port: #selection; fromOutsidePort: #focusOne.
